Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall scattering explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective.
Blue has been an important colour in art and decoration since ancient times. The semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and later, in the Renaissance, to make the pigment ultramarine, the most expensive of all pigments. In the eighth century Chinese artists used cobalt blue to colour fine blue and white porcelain. In the Middle Ages, European artists used it in the windows of Cathedrals. Europeans wore clothing coloured with the vegetable dye woad until it was replaced by the finer indigo from America. In the 19th century, synthetic blue dyes and pigments gradually replaced mineral pigments and synthetic dyes. Dark blue became a common colour for military uniforms and later, in the late 20th century, for business suits. Because blue has commonly been associated with harmony, it was chosen as the colour of the flags of the United Nations and the European Union.
Surveys in the US and Europe show that blue is the colour most commonly associated with harmony, faithfulness, confidence, distance, infinity, the imagination, cold, and sometimes with sadness. In US and European public opinion polls it is the most popular colour, chosen by almost half of both men and women as their favourite colour. The same surveys also showed that blue was the colour most associated with the masculine, just ahead of black, and was also the colour most associated with intelligence, knowledge, calm and concentration.

Blue is the colour of light between violet and green on the visible spectrum. Hues of blue include indigo and ultramarine, closer to violet; pure blue, without any mixture of other colours; Cyan, which is midway in the spectrum between blue and green, and the other blue-greens turquoise, teal, and aquamarine.
Blue also varies in shade or tint; darker shades of blue contain black or grey, while lighter tints contain white. Darker shades of blue include ultramarine, cobalt blue, navy blue, and Prussian blue; while lighter tints include sky blue, azure, and Egyptian blue. (For a more complete list see the List of colours).
Blue pigments were originally made from minerals such as lapis lazuli, cobalt and azurite, and blue dyes were made from plants; usually woad in Europe, and Indigofera tinctoria, or true indigo, in Asia and Africa. Today most blue pigments and dyes are made by a chemical process.
The modern English word blue comes from Middle English bleu or blewe, from the Old French bleu, a word of Germanic origin, related to the Old High German word blao. In heraldry, the word azure is used for blue.
In Russian and some other languages, there is no single word for blue, but rather different words for light blue (голубой, goluboy) and dark blue (синий, siniy). See Colour term.
Several languages, including Japanese, Thai, Korean, and Lakota Sioux, use the same word to describe blue and green. For example, in Vietnamese the colour of both tree leaves and the sky is xanh. In Japanese, the word for blue (青 ao) is often used for colours that English speakers would refer to as green, such as the colour of a traffic signal meaning "go". (For more on this subject, see Distinguishing blue from green in language)
Linguistic research indicates that languages do not begin by having a word for the colour blue. Colour names often developed individually in natural languages, typically beginning with black and white (or dark and light), and then adding red, and only much later – usually as the last main category of colour accepted in a language – adding the colour blue, probably when blue pigments could be manufactured reliably in the culture using that language.

Human eyes perceive blue when observing light which has a dominant wavelength of roughly 450–495 nanometres. Blues with a higher frequency and thus a shorter wavelength gradually look more violet, while those with a lower frequency and a longer wavelength gradually appear more green. Pure blue, in the middle, has a wavelength of 470 nanometres.
Isaac Newton included blue as one of the seven colours in his first description the visible spectrum, He chose seven colours because that was the number of notes in the musical scale, which he believed was related to the optical spectrum. He included indigo, the hue between blue and violet, as one of the separate colours, though today it is usually considered a hue of blue.
In painting and traditional colour theory, blue is one of the three primary colours of pigments (red, yellow, blue), which can be mixed to form a wide gamut of colours. Red and blue mixed together form violet, blue and yellow together form green. Mixing all three primary colours together produces a dark grey. From the Renaissance onwards, painters used this system to create their colours. (See RYB colour system.)
The RYB model was used for colour printing by Jacob Christoph Le Blon as early as 1725. Later, printers discovered that more accurate colours could be created by using combinations of magenta, cyan, yellow and black ink, put onto separate inked plates and then overlaid one at a time onto paper. This method could produce almost all the colours in the spectrum with reasonable accuracy.
In the 19th century the Scottish physicist James Clerk Maxwell found a new way of explaining colours, by the wavelength of their light. He showed that white light could be created by combining red, blue and green light, and that virtually all colours could be made by different combinations of these three colours. His idea, called additive colour or the RGB colour model, is used today to create colours on televisions and computer screens. The screen is covered by tiny pixels, each with three fluorescent elements for creating red, green and blue light. If the red, blue and green elements all glow at once, the pixel looks white. As the screen is scanned from behind with electrons, each pixel creates its own designated colour, composing a complete picture on the screen.
On the HSV colour wheel, the complement of blue is yellow; that is, a colour corresponding to an equal mixture of red and green light. On a colour wheel based on traditional colour theory (RYB) where blue was considered a primary colour, its complementary colour is considered to be orange (based on the Munsell colour wheel).
Blue pigments were made from minerals, especially lapis lazuli and azurite (Cu
2). These minerals were crushed, ground into powder, and then mixed with a quick-drying binding agent, such as egg yolk (tempera painting); or with a slow-drying oil, such as linseed oil, for oil painting. To make blue stained glass, cobalt blue (cobalt(II) aluminate: CoAl
4)pigment was mixed with the glass. Other common blue pigments made from minerals are ultramarine (Na8-10Al
24S2-4), cerulean blue (primarily cobalt (II) stanate: Co
4), and Prussian blue (milori blue: primarily Fe
Natural dyes to colour cloth and tapestries were made from plants. Woad and true indigo were used to produce indigo dye used to colour fabrics blue or indigo. Since the 18th century, natural blue dyes have largely been replaced by synthetic dyes.
"Reflex blue" used to be the name of a common blue pigment in ink manufacturing. In the 1960s, the name was adopted into the proprietary Pantone Matching System (PMS) to refer to this specific pigment. Pantone "Reflex Blue" has the particularity of being identified only by this name, and not by a number code.
Of the colours in the visible spectrum of light, blue has a very short wavelength, while red has the longest wavelength. When sunlight passes through the atmosphere, the blue wavelengths are scattered more widely by the oxygen and nitrogen molecules, and more blue comes to our eyes. This effect is called Rayleigh scattering, after Lord Rayleigh, the British physicist who discovered it. It was confirmed by Albert Einstein in 1911.
Near sunrise and sunset, most of the light we see comes in nearly tangent to the Earth's surface, so that the light's path through the atmosphere is so long that much of the blue and even green light is scattered out, leaving the sun rays and the clouds it illuminates red. Therefore, when looking at the sunset and sunrise, the colour red is more perceptible than any of the other colours.
The sea is seen as blue for largely the same reason: the water absorbs the longer wavelengths of red and reflects and scatters the blue, which comes to the eye of the viewer. The colour of the sea is also affected by the colour of the sky, reflected by particles in the water; and by algae and plant life in the water, which can make it look green; or by sediment, which can make it look brown.
The farther away an object is, the more blue it often appears to the eye. For example, mountains in the distance often appear blue. This is the effect of atmospheric perspective; the farther an object is away from the viewer, the less contrast there is between the object and its background colour, which is usually blue. In a painting where different parts of the composition are blue, green and red, the blue will appear to be more distant, and the red closer to the viewer. The cooler a colour is, the more distant it seems.
Blue giants are hot and luminous stars with surface temperatures exceeding 10,000 K. The largest blue supergiant stars are extremely massive and energetic, and are usually unstable. They are generally short-lived, either exploding in a supernova or periodically shedding their outer layers to become red giants.
Blue eyes do not actually contain any blue pigment. Eye colour is determined by two factors: the pigmentation of the eye's iris and the scattering of light by the turbid medium in the stroma of the iris. In humans, the pigmentation of the iris varies from light brown to black. The appearance of blue, green, and hazel eyes results from the Tyndall scattering of light in the stroma, an optical effect similar to what accounts for the blueness of the sky. The irises of the eyes of people with blue eyes contain less dark melanin than those of people with brown eyes, which means that they absorb less short-wavelength blue light, which is instead reflected out to the viewer. Eye colour also varies depending on the lighting conditions, especially for lighter-coloured eyes.
Blue eyes are most common in Ireland, the Baltic Sea area and Northern Europe, and are also found in Eastern, Central, and Southern Europe. Blue eyes are also found in parts of Western Asia, most notably in Afghanistan, Syria, Iraq, and Iran. In Estonia, 99% of people have blue eyes. In Denmark 30 years ago, only 8% of the population had brown eyes, though through immigration, today that number is about 11%. In Germany, about 75% have blue eyes.
In the United States, as of 2006, one out of every six people, or 16.6% of the total population, and 22.3% of the white population, have blue eyes, compared with about half of Americans born in 1900, and a third of Americans born in 1950. Blue eyes are becoming less common among American children. In the US, boys are 3–5 per cent more likely to have blue eyes than girls.
Lasers emitting in the blue region of the spectrum became widely available to the public in 2010 with the release of inexpensive high-powered 445-447 nm laser diode technology. Previously the blue wavelengths were accessible only through DPSS which are comparatively expensive and inefficient, however these technologies are still widely used by the scientific community for applications including optogenetics, Raman spectroscopy, and particle image velocimetry, due to their superior beam quality. Blue gas lasers are also still commonly used for holography, DNA sequencing, optical pumping, and other scientific and medical applications.
Blue was a latecomer among colours used in art and decoration, as well as language and literature. Reds, blacks, browns, and ochres are found in cave paintings from the Upper Paleolithic period, but not blue. Blue was also not used for dyeing fabric until long after red, ochre, pink and purple. This is probably due to the perennial difficulty of making good blue dyes and pigments. The earliest known blue dyes were made from plants – woad in Europe, indigo in Asia and Africa, while blue pigments were made from minerals, usually either lapis lazuli or azurite.
Lapis lazuli, a semi-precious stone, has been mined in Afghanistan for more than three thousand years, and was exported to all parts of the ancient world. In Iran and Mesopotamia, it was used to make jewellery and vessels. In Egypt, it was used for the eyebrows on the funeral mask of King Tutankhamun (1341–1323 BC). Importing lapis lazuli by caravan across the desert from Afghanistan to Egypt was very expensive. Beginning in about 2500 BC, the ancient Egyptians began to produce their own blue pigment known as Egyptian blue by grinding silica, lime, copper, and alkalai, and heating it to 800 or 900 °C (1,470 or 1,650 °F). This is considered the first synthetic pigment. Egyptian blue was used to paint wood, papyrus and canvas, and was used to colour a glaze to make faience beads, inlays, and pots. It was particularly used in funeral statuary and figurines and in tomb paintings. Blue was considered a beneficial colour which would protect the dead against evil in the afterlife. Blue dye was also used to colour the cloth in which mummies were wrapped.
In Egypt blue was associated with the sky and with divinity. The Egyptian god Amun could make his skin blue so that he could fly, invisible, across the sky. Blue could also protect against evil; many people around the Mediterranean still wear a blue amulet, representing the eye of God, to protect them from misfortune. Blue glass was manufactured in Mesopotamia and Egypt as early as 2500 BC, using the same copper ingredients as Egyptian blue pigment. They also added cobalt, which produced a deeper blue, the same blue produced in the Middle Ages in the stained glass windows of the cathedrals of Saint-Denis and Chartres. The Ishtar Gate of ancient Babylon (604–562 BC) was decorated with deep blue glazed bricks used as a background for pictures of lions, dragons and aurochs.
The ancient Greeks classified colours by whether they were light or dark, rather than by their hue. The Greek word for dark blue, kyaneos, could also mean dark green, violet, black or brown. The ancient Greek word for a light blue, glaukos, also could mean light green, grey, or yellow. The Greeks imported indigo dye from India, calling it indikon. They used Egyptian blue in the wall paintings of Knossos, in Crete, (2100 BC). It was not one of the four primary colours for Greek painting described by Pliny the Elder (red, yellow, black, and white), but nonetheless it was used as a background colour behind the friezes on Greek temples and to colour the beards of Greek statues.
The Romans also imported indigo dye, but blue was the colour of working class clothing; the nobles and rich wore white, black, red or violet. Blue was considered the colour of mourning, and the colour of barbarians. Julius Caesar reported that the Celts and Germans dyed their faces blue to frighten their enemies, and tinted their hair blue when they grew old. Nonetheless, the Romans made extensive use of blue for decoration. According to Vitruvius, they made dark blue pigment from indigo, and imported Egyptian blue pigment. The walls of Roman villas in Pompeii had frescoes of brilliant blue skies, and blue pigments were found in the shops of colour merchants. The Romans had many different words for varieties of blue, including caeruleus, caesius, glaucus, cyaneus, lividus, venetus, aerius, and ferreus, but two words, both of foreign origin, became the most enduring; blavus, from the Germanic word blau, which eventually became bleu or blue; and azureus, from the Arabic word lazaward, which became azure.
Dark blue was widely used in the decoration of churches in the Byzantine Empire. In Byzantine art Christ and the Virgin Mary usually wore dark blue or purple. Blue was used as a background colour representing the sky in the magnificent mosaics which decorated Byzantine churches.
In the Islamic world, blue was of secondary importance to green, believed to be the favourite colour of the Prophet Mohammed. At certain times in Moorish Spain and other parts of the Islamic world, blue was the colour worn by Christians and Jews, because only Muslims were allowed to wear white and green. Dark blue and turquoise decorative tiles were widely used to decorate the facades and interiors of mosques and palaces from Spain to Central Asia. Lapis lazuli pigment was also used to create the rich blues in Persian miniatures.
In the art and life of Europe during the early Middle Ages, blue played a minor role. The nobility wore red or purple, while only the poor wore blue clothing, coloured with poor-quality dyes made from the woad plant. Blue played no part in the rich costumes of the clergy or the architecture or decoration of churches. This changed dramatically between 1130 and 1140 in Paris, when the Abbe Suger rebuilt the Saint Denis Basilica. He installed stained glass windows coloured with cobalt, which, combined with the light from the red glass, filled the church with a bluish violet light. The church became the marvel of the Christian world, and the colour became known as the "bleu de Saint-Denis". In the years that followed even more elegant blue stained glass windows were installed in other churches, including at Chartres Cathedral and Sainte-Chapelle in Paris.
Another important factor in the increased prestige of the colour blue in the 12th century was the veneration of the Virgin Mary, and a change in the colours used to depict her clothing. In earlier centuries her robes had usually been painted in sombre black, grey, violet, dark green or dark blue. In the 12th century the Roma Catholic Church dictated that painters in Italy (and the rest of Europe consequently) to paint the Virgin Mary with the new most expensive pigment imported from Asia; ultramarine. Blue became associated with holiness, humility and virtue.
Ultramarine was made from lapis lazuli, from the mines of Badakshan, in the mountains of Afghanistan, near the source of the Oxus River. The mines were visited by Marco Polo in about 1271; he reported, "here is found a high mountain from which they extract the finest and most beautiful of blues." Ground lapis was used in Byzantine manuscripts as early as the 6th century, but it was impure and varied greatly in colour. Ultramarine refined out the impurities through a long and difficult process, creating a rich and deep blue. It was called bleu outremer in French and blu oltremare in Italian, since it came from the other side of the sea. It cost far more than any other colour, and it became the luxury colour for the Kings and Princes of Europe.
King Louis IX of France, better known as Saint Louis (1214–1270), became the first king of France to regularly dress in blue. This was copied by other nobles. Paintings of the mythical King Arthur began to show him dressed in blue. The coat of arms of the kings of France became an azure or light blue shield, sprinkled with golden fleur-de-lis or lilies. Blue had come from obscurity to become the royal colour.
Once blue became the colour of the king, it also became the colour of the wealthy and powerful in Europe. In the Middle Ages in France and to some extent in Italy, the dyeing of blue cloth was subject to license from the crown or state. In Italy, the dyeing of blue was assigned to a specific guild, the tintori di guado, and could not be done by anyone else without severe penalty. The wearing of blue implied some dignity and some wealth.
Besides ultramarine, several other blues were widely used in the Middle Ages and later in the Renaissance. Azurite, a form of copper carbonate, was often used as a substitute for ultramarine. The Romans used it under the name lapis armenius, or Armenian stone. The British called it azure of Amayne, or German azure. The Germans themselves called it bergblau, or mountain stone. It was mined in France, Hungary, Spain and Germany, and it made a pale blue with a hint of green, which was ideal for painting skies. It was a favourite background colour of the German painter Albrecht Dürer.
Another blue often used in the Middle Ages was called tournesol or folium. It was made from the plant Crozophora tinctoria, which grew in the south of France. It made a fine transparent blue valued in medieval manuscripts.
Another common blue pigment was smalt, which was made by grinding blue cobalt glass into a fine powder. It made a deep violet blue similar to ultramarine, and was vivid in frescoes, but it lost some of its brilliance in oil paintings. It became especially popular in the 17th century, when ultramarine was difficult to obtain. It was employed at times by Titian, Tintoretto, Veronese, El Greco, Van Dyck, Rubens and Rembrandt.
In the Renaissance, a revolution occurred in painting; artists began to paint the world as it was actually seen, with perspective, depth, shadows, and light from a single source. Artists had to adapt their use of blue to the new rules. In medieval paintings, blue was used to attract the attention of the viewer to the Virgin Mary, and identify her. In Renaissance paintings, artists tried to create harmonies between blue and red, lightening the blue with lead white paint and adding shadows and highlights. Raphael was a master of this technique, carefully balancing the reds and the blues so no one colour dominated the picture.
Ultramarine was the most prestigious blue of the Renaissance, and patrons sometimes specified that it be used in paintings they commissioned. The contract for the Madone des Harpies by Andrea del Sarto (1514) required that the robe of the Virgin Mary be coloured with ultramarine costing "at least five good florins an ounce." Good ultramarine was more expensive than gold; in 1508 the German painter Albrecht Dürer reported in a letter that he had paid twelve ducats – the equivalent of forty-one grams of gold – for just thirty grams of ultramarine.
Often painters or clients saved money by using less expensive blues, such as azurite smalt, or pigments made with indigo, but this sometimes caused problems. Pigments made from azurite were less expensive, but tended to turn dark and green with time. An example is the robe of the Virgin Mary in The Madonna and Child Enthroned with Saints by Raphael in the Metropolitan Museum in New York. The Virgin Mary's azurite blue robe has degraded into a greenish-black.
The introduction of oil painting changed the way colours looked and how they were used. Ultramarine pigment, for instance, was much darker when used in oil painting than when used in tempera painting, in frescoes. To balance their colours, Renaissance artists like Raphael added white to lighten the ultramarine. The sombre dark blue robe of the Virgin Mary became a brilliant sky blue. Titian created his rich blues by using many thin glazes of paint of different blues and violets which allowed the light to pass through, which made a complex and luminous colour, like stained glass. He also used layers of finely ground or coarsely ground ultramarine, which gave subtle variations to the blue.
In about the 9th century, Chinese artisans abandoned the Han blue colour they had used for centuries, and began to use cobalt blue, made with cobalt salts of alumina, to manufacture fine blue and white porcelain, The plates and vases were shaped, dried, the paint applied with a brush, covered with a clear glaze, then fired at a high temperature. Beginning in the 14th century, this type of porcelain was exported in large quantity to Europe where it inspired a whole style of art, called Chinoiserie. European courts tried for many years to imitate Chinese blue and white porcelain, but only succeeded in the 18th century after a missionary brought the secret back from China.
Other famous white and blue patterns appeared in Delft, Meissen, Staffordshire, and Saint Petersburg, Russia.
While blue was an expensive and prestigious colour in European painting, it became a common colour for clothing during the Renaissance. The rise of the colour blue in fashion in the 12th and 13th centuries led to a blue dye industry in several cities, notably Amiens, Toulouse, and Erfurt. They made a dye called pastel from woad, a plant common in Europe, which had been used to make blue dye by the Celts and German tribes. Blue became a colour worn by domestics and artisans, not just nobles. In 1570, when Pope Pius V listed the colours that could be used for ecclesiastical dress and for altar decoration, he excluded blue, because he considered it too common.
The process of making blue with woad was long and noxious – it involved soaking the leaves of the plant for from three days to a week in human urine, ideally urine from men who had been drinking a great deal of alcohol, which was said to improve the colour. The fabric was then soaked for a day in the resulting mixture, then put out in the sun, where as it dried it turned blue.
The pastel industry was threatened in the 15th century by the arrival from India of the same dye (indigo), obtained from a shrub widely grown in Asia. The Asian indigo dye precursors is more readily obtained. In 1498, Vasco de Gama opened a trade route to import indigo from India to Europe. In India, the indigo leaves were soaked in water, fermented, pressed into cakes, dried into bricks, then carried to the ports London, Marseille, Genoa, and Bruges. Later, in the 17th century, the British, Spanish, and Dutch established indigo plantations in Jamaica, South Carolina, the Virgin Islands and South America, and began to import American indigo to Europe.
The countries with large and prosperous pastel industries tried to block the use of indigo. The German government outlawed the use of indigo in 1577, describing it as a "pernicious, deceitful and corrosive substance, the Devil's dye." In France, Henry IV, in an edict of 1609, forbade under pain of death the use of "the false and pernicious Indian drug". It was forbidden in England until 1611, when British traders established their own indigo industry in India and began to import it into Europe.
The efforts to block indigo were in vain; the quality of indigo blue was too high and the price too low for pastel made from woad to compete. In 1737 both the French and German governments finally allowed the use of indigo. This ruined the dye industries in Toulouse and the other cities that produced pastel, but created a thriving new indigo commerce to seaports such as Bordeaux, Nantes and Marseille.
Another war of the blues took place at the end of the 19th century, between indigo and synthetic indigo, discovered in 1868 by the German chemist Johann Friedrich Wilhelm Adolf von Baeyer. The German chemical firm BASF put the new dye on the market in 1897, in direct competition with the British-run indigo industry in India, which produced most of the world's indigo. In 1897 Britain sold ten thousand tons of natural indigo on the world market, while BASF sold six hundred tons of synthetic indigo. The British industry cut prices and reduced the salaries of its workers, but it was unable to compete; the synthetic indigo was more pure, made a more lasting blue, and was not dependent upon good or bad harvests. In 1911, India sold only 660 tons of natural indigo, while BASF sold 22,000 tons of synthetic indigo. In 2002, more than 38,000 tons of synthetic indigo was produced, often for the production of blue jeans.
In the 17th century, Frederick William, Elector of Brandenburg, was one of the first rulers to give his army blue uniforms. The reasons were economic; the German states were trying to protect their pastel dye industry against competition from imported indigo dye. When Brandenburg became the Kingdom of Prussia in 1701, the uniform colour was adopted by the Prussian army. Most German soldiers wore dark blue uniforms until the First World War, with the exception of the Bavarians, who wore light blue.
Thanks in part to the availability of indigo dye, the 18th century saw the widespread use of blue military uniforms. Prior to 1748, British naval officers simply wore upper-class civilian clothing and wigs. In 1748, the British uniform for naval officers was officially established as an embroidered coat of the colour then called marine blue, now known as navy blue. When the Continental Navy of the United States was created in 1775, it largely copied the British uniform and colour.
In the late 18th century, the blue uniform became a symbol of liberty and revolution. In October 1774, even before the United States declared its independence, George Mason and one hundred Virginia neighbours of George Washington organised a voluntary militia unit (the Fairfax County Independent Company of Volunteers) and elected Washington the honorary commander. For their uniforms they chose blue and buff, the colours of the Whig Party, the opposition party in England, whose policies were supported by George Washington and many other patriots in the American colonies.
When the Continental Army was established in 1775 at the outbreak of the American Revolution, the first Continental Congress declared that the official uniform colour would be brown, but this was not popular with many militias, whose officers were already wearing blue. In 1778 the Congress asked George Washington to design a new uniform, and in 1779 Washington made the official colour of all uniforms blue and buff. Blue continued to be the colour of the field uniform of the US Army until 1902, and is still the colour of the dress uniform.
In France the Gardes Françaises, the elite regiment which protected Louis XVI, wore dark blue uniforms with red trim. In 1789, the soldiers gradually changed their allegiance from the king to the people, and they played a leading role in the storming of the Bastille. After the fall of Bastille, a new armed force, the Garde Nationale, was formed under the command of the Marquis de Lafayette, who had served with George Washington in America. Lafayette gave the Garde Nationale dark blue uniforms similar to those of the Continental Army. Blue became the colour of the revolutionary armies, opposed to the white uniforms of the Royalists and the Austrians.
Napoleon Bonaparte abandoned many of the doctrines of the French Revolution but he kept blue as the uniform colour for his army, although he had great difficulty obtaining the blue dye, since the British controlled the seas and blocked the importation of indigo to France. Napoleon was forced to dye uniforms with woad, which had an inferior blue colour. The French army wore a dark blue uniform coat with red trousers until 1915, when it was found to be a too visible target on the battlefields of World War I. It was replaced with uniforms of a light blue-grey colour called horizon blue.
Blue was the colour of liberty and revolution in the 18th century, but in the 19th it increasingly became the colour of government authority, the uniform colour of policemen and other public servants. It was considered serious and authoritative, without being menacing. In 1829, when Robert Peel created the first London Metropolitan Police, he made the colour of the uniform jacket a dark, almost black blue, to make the policemen look different from the red coated soldiers, who had on occasion been used to enforce order. The traditional blue jacket with silver buttons of the London "bobbie" was not abandoned until the mid-1990s, when it was replaced for all but formal occasions by a jumper or sweater of the colour officially known as NATO blue.
Navy blue is one of the most popular school uniform colours, with the Toronto Catholic District School Board adopting a dress code policy which requires students system-wide to wear white tops and navy blue bottoms.
During the 17th and 18th centuries, chemists in Europe tried to discover a way to create synthetic blue pigments, avoiding the expense of importing and grinding lapis lazuli, azurite and other minerals. The Egyptians had created a synthetic colour, Egyptian blue, three thousand years BC, but the formula had been lost. The Chinese had also created synthetic pigments, but the formula was not known in the west.
In 1709 a German druggist and pigment maker named Johann Jacob Diesbach accidentally discovered a new blue while experimenting with potassium and iron sulphides. The new colour was first called Berlin blue, but later became known as Prussian blue. By 1710 it was being used by the French painter Antoine Watteau, and later his successor Nicolas Lancret. It became immensely popular for the manufacture of wallpaper, and in the 19th century was widely used by French impressionist painters.
Beginning in the 1820s, Prussian blue was imported into Japan through the port of Nagasaki. It was called bero-ai, or Berlin blue, and it became popular because it did not fade like traditional Japanese blue pigment, ai-gami, made from the dayflower. Prussian blue was used by both Hokusai, in his famous wave paintings, and Hiroshige.
In 1824 the Societé pour l'Encouragement d'Industrie in France offered a prize for the invention of an artificial ultramarine which could rival the natural colour made from lapis lazuli. The prize was won in 1826 by a chemist named Jean Baptiste Guimet, but he refused to reveal the formula of his colour. In 1828, another scientist, Christian Gmelin then a professor of chemistry in Tübingen, found the process and published his formula. This was the beginning of new industry to manufacture artificial ultramarine, which eventually almost completely replaced the natural product.
In 1878 a German chemist named a. Von Baeyer discovered a synthetic substitute for indigotine, the active ingredient of indigo. This product gradually replaced natural indigo, and after the end of the First World War, it brought an end to the trade of indigo from the East and West Indies.
In 1901 a new synthetic blue dye, called Indanthrone blue, was invented, which had even greater resistance to fading during washing or in the sun. This dye gradually replaced artificial indigo, whose production ceased in about 1970. Today almost all blue clothing is dyed with an indanthrone blue.
The invention of new synthetic pigments in the 18th and 19th centuries considerably brightened and expanded the palette of painters. J.M.W. Turner experimented with the new cobalt blue, and of the twenty colours most used by the Impressionists, twelve were new and synthetic colours, including cobalt blue, ultramarine and cerulean blue.
Another important influence on painting in the 19th century was the theory of complementary colours, developed by the French chemist Michel Eugene Chevreul in 1828 and published in 1839. He demonstrated that placing complementary colours, such as blue and yellow-orange or ultramarine and yellow, next to each other heightened the intensity of each colour "to the apogee of their tonality." In 1879 an American physicist, Ogden Rood, published a book charting the complementary colours of each colour in the spectrum. This principle of painting was used by Claude Monet in his Impression – Sunrise – Fog (1872), where he put a vivid blue next to a bright orange sun, (1872) and in Régate à Argenteuil (1872), where he painted an orange sun against blue water. The colours brighten each other. Renoir used the same contrast of cobalt blue water and an orange sun in Canotage sur la Seine (1879–1880). Both Monet and Renoir liked to use pure colours, without any blending.
Monet and the impressionists were among the first to observe that shadows were full of colour. In his La Gare Saint-Lazare, the grey smoke, vapour and dark shadows are actually composed of mixtures of bright pigment, including cobalt blue, cerulean blue, synthetic ultramarine, emerald green, Guillet green, chrome yellow, vermilion and ecarlate red. Blue was a favourite colour of the impressionist painters, who used it not just to depict nature but to create moods, feelings and atmospheres. Cobalt blue, a pigment of cobalt oxide-aluminium oxide, was a favourite of Auguste Renoir and Vincent van Gogh. It was similar to smalt, a pigment used for centuries to make blue glass, but it was much improved by the French chemist Louis Jacques Thénard, who introduced it in 1802. It was very stable but extremely expensive. Van Gogh wrote to his brother Theo, "'Cobalt [blue] is a divine colour and there is nothing so beautiful for putting atmosphere around things ..."
Van Gogh described to his brother Theo how he composed a sky: "The dark blue sky is spotted with clouds of an even darker blue than the fundamental blue of intense cobalt, and others of a lighter blue, like the bluish white of the Milky Way ... the sea was very dark ultramarine, the shore a sort of violet and of light red as I see it, and on the dunes, a few bushes of prussian blue."
Blue had first become the high fashion colour of the wealthy and powerful in Europe in the 13th century, when it was worn by Louis IX of France, better known as Saint Louis (1214-1270). Wearing blue implied dignity and wealth, and blue clothing was restricted to the nobility. However, blue was replaced by black as the power colour in the 14th century, when European princes, and then merchants and bankers, wanted to show their seriousness, dignity and devoutness (see Black).
Blue gradually returned to court fashion in the 17th century, as part of a palette of peacock-bright colours shown off in extremely elaborate costumes. The modern blue business suit has its roots in England in the middle of the 17th century. Following the London plague of 1665 and the London fire of 1666, King Charles II of England ordered that his courtiers wear simple coats, waistcoats and breeches, and the palette of colours became blue, grey, white and buff. Widely imitated, this style of men's fashion became almost a uniform of the London merchant class and the English country gentleman.
During the American Revolution, the leader of the Whig Party in England, Charles James Fox, wore a blue coat and buff waistcoat and breeches, the colours of the Whig Party and of the uniform of George Washington, whose principles he supported. The men's suit followed the basic form of the military uniforms of the time, particularly the uniforms of the cavalry.
In the early 19th century, during the Regency of the future King George IV, the blue suit was revolutionised by a courtier named George Beau Brummel. Brummel created a suit that closely fitted the human form. The new style had a long tail coat cut to fit the body and long tight trousers to replace the knee-length breeches and stockings of the previous century. He used plain colours, such as blue and grey, to concentrate attention on the form of the body, not the clothes. Brummel observed, "If people turn to look at you in the street, you are not well dressed." This fashion was adopted by the Prince Regent, then by London society and the upper classes. Originally the coat and trousers were different colours, but in the 19th century the suit of a single colour became fashionable. By the late 19th century the black suit had become the uniform of businessmen in England and America. In the 20th century, the black suit was largely replaced by the dark blue or grey suit.
At the beginning of the 20th century, many artists recognised the emotional power of blue, and made it the central element of paintings. During his Blue Period (1901–1904) Pablo Picasso used blue and green, with hardly any warm colours, to create a melancholy mood. In Russia, the symbolist painter Pavel Kuznetsov and the Blue Rose art group (1906–1908) used blue to create a fantastic and exotic atmosphere. In Germany, Wassily Kandinsky and other Russian émigrés formed the art group called Der Blaue Reiter (The Blue Rider), and used blue to symbolise spirituality and eternity. Henri Matisse used intense blues to express the emotions he wanted viewers to feel. Matisse wrote, "A certain blue penetrates your soul."
In the art of the second half of the 20th century, painters of the abstract expressionist movement began to use blue and other colours in pure form, without any attempt to represent anything, to inspire ideas and emotions. Painter Mark Rothko observed that colour was "only an instrument;" his interest was "in expressing human emotions tragedy, ecstasy, doom, and so on."
In fashion blue, particularly dark blue, was seen as a colour which was serious but not grim. In the mid-20th century, blue passed black as the most common colour of men's business suits, the costume usually worn by political and business leaders. Public opinion polls in the United States and Europe showed that blue was the favourite colour of over fifty per cent of respondents. Green was far behind with twenty per cent, while white and red received about eight per cent each.
In 1873 a German immigrant in San Francisco, Levi Strauss, invented a sturdy kind of work trousers, made of denim fabric and coloured with indigo dye, called blue jeans. In 1935, they were raised to the level of high fashion by Vogue magazine. Beginning in the 1950s, they became an essential part of uniform of young people in the United States, Europe, and around the world.
Blue was also seen as a colour which was authoritative without being threatening. Following the Second World War, blue was adopted as the colour of important international organisations, including the United Nations, the Council of Europe, UNESCO, the European Union, and NATO. United Nations peacekeepers wear blue helmets to stress their peacekeeping role. Blue is used by the NATO Military Symbols for Land Based Systems to denote friendly forces, hence the term "blue on blue" for friendly fire, and Blue Force Tracking for location of friendly units. The People's Liberation Army of China (formerly known as the "Red Army") uses the term "Blue Army" to refer to hostile forces during exercises.
The 20th century saw the invention of new ways of creating blue, such as chemiluminescence, making blue light through a chemical reaction.
In the 20th century, it also became possible to own your own colour of blue. The French artist Yves Klein, with the help of a French paint dealer, created a specific blue called International Klein blue, which he patented. It was made of ultramarine combined with a resin called Rhodopa, which gave it a particularly brilliant colour. The baseball team the Los Angeles Dodgers developed its own blue, called Dodger blue, and several American universities invented new blues for their colours.
With the dawn of the World Wide Web, blue has become the standard colour for hyperlinks in graphic browsers (though in most browsers links turn purple if you visit their target), to make their presence within text obvious to readers.
Various shades of blue are used as the national colours for many nations.
Many sporting teams make blue their official colour, or use it as detail on kit of a different colour. In addition, the colour is present on the logos of many sports associations. Along with red, blue is the most commonly used non-white colours for teams.
In international association football, blue is a common colour on kits, as a majority of nations wear the colours of their national flag. A notable exception is four-time FIFA World Cup winners Italy, who wear a blue kit based on the Azzuro Savoia (Savoy blue) of the royal House of Savoy which unified the Italian states. The team themselves are known as Gli Azzurri (the Blues). Another World Cup winning nation with a blue shirt is France, who are known as Les Bleus (the Blues). Two neighbouring countries with two World Cup victories each, Argentina and Uruguay wear a light blue shirt, the former with white stripes. Uruguay are known as the La Celeste, Spanish for 'the sky blue one', while Argentina are known as Los Albicelestes, Spanish for 'the sky blue and whites'.
Blue features on the logo of football's governing body FIFA, as well as featuring highly in the design of their website. The European governing body of football, UEFA, uses two tones of blue to create a map of Europe in the centre of their logo. The Asian Football Confederation, Oceania Football Confederation and CONCACAF (the governing body of football in North and Central America and the Caribbean) use blue text on their logos.
In Major League Baseball, the premier baseball league in the United States and Canada, blue is one of the three colours, along with white and red, on the league's official logo. A team from Toronto, Ontario are nicknamed the Blue Jays. Seventeen other teams either regularly feature blue hats or utilise the colour in their uniforms.
The National Basketball Association, the premier basketball league in the United States and Canada, also has blue as one of the colours on their logo, along with red and white also, as did its female equivalent, the WNBA, until March 28, 2011, when the latter adopted an orange and white logo. Former NBA player Theodore Edwards was nicknamed "Blue". Fifteen NBA teams feature the colour in their uniforms.
The National Football League, the premier American football league in the United States, also uses blue as one of three colours, along with white and red, on their official logo. Thirteen NFL teams prominently feature the colour .
The National Hockey League, the premier Ice hockey league in Canada and the United States, uses blue on its official logo. Blue is the main colour of many teams in the league: the Buffalo Sabres, Columbus Blue Jackets, Edmonton Oilers, New York Islanders, New York Rangers, St. Louis Blues, Toronto Maple Leafs, Tampa Bay Lightning, Vancouver Canucks and the Winnipeg Jets.
The Main Building and its two annexes are covered with a total of 150,000 traditional Korean blue roof tiles (hence, the name "Blue House" is also commonly used when referring to Cheongwadae).
Beyoncé Giselle Knowles-Carter (; born September 4, 1981) is an American singer, songwriter, actress, director, record producer and dancer. Born and raised in Houston, Texas, Beyoncé performed in various singing and dancing competitions as a child. She rose to fame in the late 1990s as lead singer of the R&B girl-group Destiny's Child. Managed by her father, Mathew Knowles, the group became one of the best-selling girl groups in history. Their hiatus saw Beyoncé's theatrical film debut in Austin Powers in Goldmember (2002), and the release of her first solo album, Dangerously in Love (2003). The album established her as a solo artist worldwide, debuting at number one on the US Billboard 200 chart and earned her five Grammy Awards. The album also featured the Billboard Hot 100 number-one singles, "Crazy in Love" and "Baby Boy".
Following the break-up of Destiny's Child in 2006, she released her second solo album, B'Day (2006), which contained her fourth number-one single, "Irreplaceable", as well as the top ten singles, "Déjà Vu", and "Beautiful Liar". Beyoncé also continued her acting career, with starring roles in The Pink Panther (2006), Dreamgirls (2006), and Obsessed (2009). Her marriage to rapper Jay-Z and her portrayal of Etta James in Cadillac Records (2008), influenced her third album, I Am... Sasha Fierce (2008), which saw the introduction of her alter-ego, Sasha Fierce and earned a record-setting six Grammy Awards in 2010, including Song of the Year for "Single Ladies (Put a Ring on It)". Beyoncé took a hiatus from music in 2010 and took over management of her career; her fourth album, 4 (2011), was subsequently mellower in tone, exploring 1970s funk, 1980s pop, and 1990s soul. Her critically acclaimed eponymous album, released in 2013 with no prior announcement, was distinguished from previous releases by its experimental production and exploration of darker themes. Her sixth album, Lemonade (2016), also received widespread critical acclaim, with many referring to it as her most personal and political work to date, and subsequently became the best-selling album of 2016. In 2018, she released Everything Is Love, a collaborative album with her husband Jay-Z, as The Carters.
Throughout her career, Beyoncé has sold over 100 million records worldwide as a solo artist, and a further 60 million records with Destiny's Child, making her one of the best-selling music artists of all time. She is a multi-platinum, Grammy-Award-winning recording artist, who is acclaimed for her thrilling vocals, videos, and live concert shows. The Recording Industry Association of America recognized Beyoncé as the Top Certified Artist in America during the 2000s decade. In 2009, Billboard named her the Top Radio Songs Artist of the Decade and the Top Female Artist of the 2000s decade. Among numerous awards and accolades, Beyoncé has won 23 Grammy Awards and is the most nominated woman in the award's history. She is also the most awarded artist at the MTV Video Music Awards, with 24 wins, including the Michael Jackson Video Vanguard Award. In 2008, she was awarded the Legend Award for Outstanding Contribution to the Arts at the World Music Awards. In 2011, Beyoncé was presented with the inaugural Millennium Award at the Billboard Music Awards. In 2014, she became the highest-paid black musician in history and was listed among Time's 100 most influential people in the world for a second year in a row. Forbes ranked her as the most powerful female in entertainment on their 2015 and 2017 lists, and in 2016, she occupied the sixth place for Time's Person of the Year. In 2016, she was awarded the Fashion Icon lifetime achievement award from the Council of Fashion Designers of America. With the release of Lemonade, Beyoncé became the first and only musical act in Billboard chart history to debut at number one with their first six solo studio albums.Blu-ray
Blu-ray or Blu-ray Disc (BD) is a digital optical disc data storage format. It was designed to supersede the DVD format, and is capable of storing several hours of video in high-definition (HDTV 720p and 1080p) and ultra high-definition resolution (2160p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, and Xbox One. The name "Blu-ray" refers to the blue laser (actually a violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs.
The plastic disc is 120 millimetres (4.7 in) in diameter and 1.2 millimetres (0.047 in) thick, the same size as DVDs and CDs. Conventional or pre-BD-XL Blu-ray discs contain 25 GB per layer, with dual-layer discs (50 GB) being the industry standard for feature-length video discs. Triple-layer discs (100 GB) and quadruple-layer discs (128 GB) are available for BD-XL re-writer drives.High-definition (HD) video may be stored on Blu-ray discs with up to 2160p resolution (3840×2160 pixels) and at up to 60 frames per second. DVD-Video discs were limited to a maximum resolution of 480p (NTSC, 720×480 pixels) or 576p (PAL, 720×576 pixels). Besides these hardware specifications, Blu-ray is associated with a set of multimedia formats.
The BD format was developed by the Blu-ray Disc Association, a group representing makers of consumer electronics, computer hardware, and motion pictures. Sony unveiled the first Blu-ray disc prototypes in October 2000, and the first prototype player was released in April 2003 in Japan. Afterwards, it continued to be developed until its official release on June 20, 2006, beginning the high-definition optical disc format war, where Blu-ray Disc competed with the HD DVD format. Toshiba, the main company supporting HD DVD, conceded in February 2008, and later released its own Blu-ray Disc player in late 2009. According to Media Research, high-definition software sales in the United States were slower in the first two years than DVD software sales. Blu-ray faces competition from video on demand (VOD) and the continued sale of DVDs. Notably, as of January 2016, 44% of U.S. broadband households had a Blu-ray player.Blue Bloods (TV series)
Blue Bloods is an American police procedural fictional drama series that airs on CBS. The series is filmed on location in New York City with occasional references to nearby suburbs. The series debuted on September 24, 2010, with episodes airing on Fridays following CSI: NY before being moved to Wednesdays at 10:00 p.m. Eastern and Pacific time and 9:00 p.m. Central and Mountain time for a four-week tryout. After four weeks, it returned to its original Friday 10:00 p.m. Eastern time slot, where it has remained since. On April 18, 2018, CBS renewed the series for a ninth season, which premiered on September 28, 2018. On April 12, 2019, CBS renewed the series for a tenth season.Blue whale
The blue whale (Balaenoptera musculus) is a marine mammal belonging to the baleen whale parvorder, Mysticeti. At up to 29.9 metres (98 ft) in length and with a maximum recorded weight of 173 tonnes (190 short tons), it is the largest animal known to have ever existed.Long and slender, the blue whale's body can be various shades of bluish-grey dorsally and somewhat lighter underneath. There are at least three distinct subspecies: B. m. musculus of the North Atlantic and North Pacific, B. m. intermedia of the Southern Ocean and B. m. brevicauda (also known as the pygmy blue whale) found in the Indian Ocean and South Pacific Ocean. B. m. indica, found in the Indian Ocean, may be another subspecies. As with other baleen whales, its diet consists almost exclusively of small crustaceans known as krill.Blue whales were abundant in nearly all the oceans on Earth until the beginning of the twentieth century. For over a century, they were hunted almost to extinction by whalers until protected by the international community in 1966. A 2002 report estimated there were 5,000 to 12,000 blue whales worldwide, in at least five populations. The IUCN estimates that there are probably between 10,000 and 25,000 blue whales worldwide today. Before whaling, the largest population was in the Antarctic, numbering approximately 239,000 (range 202,000 to 311,000). There remain only much smaller (around 2,000) concentrations in each of the eastern North Pacific, Antarctic, and Indian Ocean populations. There are two more groups in the North Atlantic, and at least two in the Southern Hemisphere. The Eastern North Pacific blue whale population had rebounded by 2014 to nearly its pre-hunting population.Columbus Blue Jackets
The Columbus Blue Jackets are a professional ice hockey team based in Columbus, Ohio. They are members of the Metropolitan Division of the Eastern Conference of the National Hockey League (NHL).
The Blue Jackets were founded as an expansion team in 2000. In their initial years, the Blue Jackets struggled, failing to win 30 games in a season until the 2005–06 season. The team qualified for the Stanley Cup playoffs for the first time in 2009, but were swept. Columbus ultimately notched their first playoff game victory in the 2014 playoffs and five years later won their first playoff series in the 2019 playoffs against the Tampa Bay Lightning, becoming the first team in NHL history to sweep a Presidents' Trophy winner in the first round.
The Blue Jackets' name and logos are inspired by Ohio's Civil War history. The Blue Jackets play their home games at Nationwide Arena in downtown Columbus, which opened in 2000. They are affiliated with the Cleveland Monsters of the AHL.Cyanobacteria
Cyanobacteria , also known as Cyanophyta, are a phylum of bacteria that obtain their energy through photosynthesis and are the only photosynthetic prokaryotes able to produce oxygen. The name cyanobacteria comes from the color of the bacteria (Greek: κυανός, translit. kyanós, lit. 'blue'). Cyanobacteria, which are prokaryotes, are also called "blue-green algae", though the term algae in modern usage is restricted to eukaryotes. The cyanobacteria appears to have originated in freshwater or a terrestrial environment.Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed.Phototrophic eukaryotes perform photosynthesis by plastids that may have their ancestry in cyanobacteria, acquired long ago via a process called endosymbiosis. These endosymbiotic cyanobacteria in eukaryotes may have evolved or differentiated into specialized organelles such as chloroplasts, etioplasts and leucoplasts.
By producing and releasing oxygen (as a byproduct of photosynthesis), cyanobacteria are thought to have converted the early oxygen-poor, reducing atmosphere into an oxidizing one, causing the Great Oxygenation Event and the "rusting of the Earth", which dramatically changed the composition of the Earth's life forms and led to the near-extinction of anaerobic organisms.Eye color
Eye color is a polygenic phenotypic character determined by two distinct factors: the pigmentation of the eye's iris and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris.In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma. The appearance of blue and green, as well as hazel eyes, results from the Tyndall scattering of light in the stroma, a phenomenon similar to that which accounts for the blueness of the sky called Rayleigh scattering. Neither blue nor green pigments are ever present in the human iris or ocular fluid. Eye color is thus an instance of structural color and varies depending on the lighting conditions, especially for lighter-colored eyes.
The brightly colored eyes of many bird species result from the presence of other pigments, such as pteridines, purines, and carotenoids. Humans and other animals have many phenotypic variations in eye color. The genetics of eye color are complicated, and color is determined by multiple genes. So far, as many as 15 genes have been associated with eye color inheritance. Some of the eye-color genes include OCA2 and HERC2. The earlier belief that blue eye color is a simple recessive trait has been shown to be incorrect. The genetics of eye color are so complex that almost any parent-child combination of eye colors can occur. However, OCA2 gene polymorphism, close to proximal 5′ regulatory region, explains most human eye-color variation.Frank Sinatra
Francis Albert Sinatra (; December 12, 1915 – May 14, 1998) was an American singer, actor and producer who was one of the most popular and influential musical artists of the 20th century. He is one of the best-selling music artists of all time, having sold more than 150 million records worldwide.Born to Italian immigrants in Hoboken, New Jersey, Sinatra began his musical career in the swing era with bandleaders Harry James and Tommy Dorsey. Sinatra found success as a solo artist after he signed with Columbia Records in 1943, becoming the idol of the "bobby soxers". He released his debut album, The Voice of Frank Sinatra, in 1946. Sinatra's professional career had stalled by the early 1950s, and he turned to Las Vegas, where he became one of its best known residency performers as part of the Rat Pack. His career was reborn in 1953 with the success of From Here to Eternity, with his performance subsequently winning an Academy Award and Golden Globe Award for Best Supporting Actor. Sinatra released several critically lauded albums, including In the Wee Small Hours (1955), Songs for Swingin' Lovers! (1956), Come Fly with Me (1958), Only the Lonely (1958) and Nice 'n' Easy (1960).
Sinatra left Capitol in 1960 to start his own record label, Reprise Records, and released a string of successful albums. In 1965, he recorded the retrospective September of My Years and starred in the Emmy-winning television special Frank Sinatra: A Man and His Music. After releasing Sinatra at the Sands, recorded at the Sands Hotel and Casino in Vegas with frequent collaborator Count Basie in early 1966, the following year he recorded one of his most famous collaborations with Tom Jobim, the album Francis Albert Sinatra & Antonio Carlos Jobim. It was followed by 1968's Francis A. & Edward K. with Duke Ellington. Sinatra retired for the first time in 1971, but came out of retirement two years later and recorded several albums and resumed performing at Caesars Palace, and reached success in 1980 with "New York, New York". Using his Las Vegas shows as a home base, he toured both within the United States and internationally until shortly before his death in 1998.
Sinatra forged a highly successful career as a film actor. After winning an Academy Award for From Here to Eternity, he starred in The Man with the Golden Arm (1955), and received critical acclaim for his performance in The Manchurian Candidate (1962). He appeared in various musicals such as On the Town (1949), Guys and Dolls (1955), High Society (1956), and Pal Joey (1957), winning another Golden Globe for the latter. Toward the end of his career, he became associated with playing detectives, including the title character in Tony Rome (1967). Sinatra would later receive the Golden Globe Cecil B. DeMille Award in 1971. On television, The Frank Sinatra Show began on ABC in 1950, and he continued to make appearances on television throughout the 1950s and 1960s. Sinatra was also heavily involved with politics from the mid-1940s, and actively campaigned for presidents such as Harry S. Truman, John F. Kennedy and Ronald Reagan. In crime, the FBI investigated Sinatra and his alleged relationship with the Mafia.
While Sinatra never learned how to read music, he had an impressive understanding of it, and he worked very hard from a young age to improve his abilities in all aspects of music. A perfectionist, renowned for his dress sense and performing presence, he always insisted on recording live with his band. His bright blue eyes earned him the popular nickname "Ol' Blue Eyes". Sinatra led a colorful personal life, and was often involved in turbulent affairs with women, such as with his second wife Ava Gardner. He later married Mia Farrow in 1966 and Barbara Marx in 1976. Sinatra had several violent confrontations, usually with journalists he felt had crossed him, or work bosses with whom he had disagreements. He was honored at the Kennedy Center Honors in 1983, was awarded the Presidential Medal of Freedom by Ronald Reagan in 1985, and the Congressional Gold Medal in 1997. Sinatra was also the recipient of eleven Grammy Awards, including the Grammy Trustees Award, Grammy Legend Award and the Grammy Lifetime Achievement Award. He was collectively included in Time magazine's compilation of the 20th century's 100 most influential people. After Sinatra's death, American music critic Robert Christgau called him "the greatest singer of the 20th century", and he continues to be seen as an iconic figure.IBM
International Business Machines Corporation (IBM) is an American multinational information technology company headquartered in Armonk, New York, with operations in over 170 countries. The company began in 1911, founded in Endicott, New York, as the Computing-Tabulating-Recording Company (CTR) and was renamed "International Business Machines" in 1924.
IBM produces and sells computer hardware, middleware and software, and provides hosting and consulting services in areas ranging from mainframe computers to nanotechnology. IBM is also a major research organization, holding the record for most U.S. patents generated by a business (as of 2019) for 26 consecutive years. Inventions by IBM include the automated teller machine (ATM), the floppy disk, the hard disk drive, the magnetic stripe card, the relational database, the SQL programming language, the UPC barcode, and dynamic random-access memory (DRAM). The IBM mainframe, exemplified by the System/360, was the dominant computing platform during the 1960s and 1970s.
IBM has continually shifted business operations by focusing on higher-value, more profitable markets. This includes spinning off printer manufacturer Lexmark in 1991 and the sale of personal computer (ThinkPad/ThinkCentre) and x86-based server businesses to Lenovo (in 2005 and 2014, respectively), and acquiring companies such as PwC Consulting (2002), SPSS (2009), The Weather Company (2016), and Red Hat (agreement announced in October 2018, actual acquisition to be in the second half of 2019). Also in 2014, IBM announced that it would go "fabless", continuing to design semiconductors, but offloading manufacturing to GlobalFoundries.
Nicknamed Big Blue, IBM is one of 30 companies included in the Dow Jones Industrial Average and one of the world's largest employers, with (as of 2017) over 380,000 employees, known as "IBMers". At least 70% of IBMers are based outside the United States, and the country with the largest number of IBMers is India. IBM employees have been awarded five Nobel Prizes, six Turing Awards, ten National Medals of Technology (USA) and five National Medals of Science (USA).India national cricket team
The India national cricket team, also known as Team India and Men in Blue, is governed by the Board of Control for Cricket in India (BCCI), and is a full member of the International Cricket Council (ICC) with Test, One Day International (ODI) and Twenty20 International (T20I) status.
Although cricket was introduced to India by European merchant sailors in the 18th century, and the first cricket club was established in Calcutta (currently known as Kolkata) in 1792, India's national cricket team did not play its first Test match until 25 June 1932 at Lord's, becoming the sixth team to be granted Test cricket status. In its first fifty years of international cricket, India was one of the weaker teams, winning only 35 of the first 196 Test matches it played. From 1932 India had to wait until 1952, almost 20 years for its first Test victory. The team, however, gained strength in the 1970s with the emergence of players such as batsmen Sunil Gavaskar and Gundappa Viswanath, all-rounder Kapil Dev and the Indian spin quartet of Erapalli Prasanna, Srinivas Venkataraghavan, Bhagwat Chandrasekhar
and Bishen Singh Bedi.
Traditionally much stronger at home than abroad, the Indian team has improved its overseas form, especially in limited-overs cricket, since the start of the 21st century, winning Test matches in Australia, England and South Africa. It has won the Cricket World Cup twice – in 1983 under the captaincy of Kapil Dev and in 2011 under the captaincy of Mahendra Singh Dhoni. After winning the 2011 World Cup, India became only the third team after West Indies and Australia to have won the World Cup more than once, and the first cricket team to win the World Cup at home. It also won the 2007 ICC World Twenty20 and 2013 ICC Champions Trophy, under the captaincy of MS Dhoni. It was also the joint champions of 2002 ICC Champions Trophy, along with Sri Lanka.
As of 19 October 2018, India is ranked first in Tests, second in ODIs and second in T20Is by the ICC. Virat Kohli is the current captain of the team across all formats, while the head coach is Ravi Shastri. The Indian cricket team has rivalries with other Test-playing nations, most notably with Pakistan, the political arch-rival of India. However, in recent times, rivalries with nations like Australia, South Africa and England have also gained prominence.Jeff Bezos

The company began as an online bookstore and has expanded to a variety of products and services, including video and audio streaming. It is currently the world's largest online sales company, as well as the world's largest provider of cloud infrastructure services via its Amazon Web Services arm.
Bezos added to his business interests when he founded aerospace company Blue Origin in 2000. A Blue Origin test flight successfully first reached space in 2015, and Blue has plans to begin commercial suborbital human spaceflight in 2019. He purchased The Washington Post in 2013 for US$250 million in cash. Bezos manages other business investments through his venture capital fund, Bezos Expeditions.
On July 27, 2017, he became the world's wealthiest person when his estimated net worth increased to just over $90 billion. Bezos's wealth surpassed $100 billion for the first time on November 24, 2017, and he was formally designated the wealthiest person in the world by Forbes on March 6, 2018, with a net worth of $112 billion. The first centi-billionaire on the Forbes wealth index, he was named the "richest man in modern history" after his net worth increased to $150 billion in July 2018.Light-emitting diode
A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. This effect is called electroluminescence. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device.Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics. The first visible-light LEDs were of low intensity and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with high light output.
Early LEDs were often used as indicator lamps, replacing small incandescent bulbs, and in seven-segment displays. Recent developments have produced white-light LEDs suitable for room lighting. LEDs have led to new displays and sensors, while their high switching rates are useful in advanced communications technology.
LEDs have many advantages over incandescent light sources, including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching. Light-emitting diodes are used in applications as diverse as aviation lighting, automotive headlamps, advertising, general lighting, traffic signals, camera flashes, lighted wallpaper and medical devices.Unlike a laser, the color of light emitted from an LED is neither coherent nor monochromatic, but the spectrum is narrow with respect to human vision, and functionally monochromatic.List of generation I Pokémon
The first generation (Generation I) of the Pokémon franchise features the original 151 fictional creatures introduced in the 1996 Game Boy games Pokémon Red and Blue.
The following list details the 151 Pokémon of Generation I in order of their numbering in the National Pokédex — an in-game electronic encyclopedia that provides various information on Pokémon. The first Pokémon, Bulbasaur, is number 001 and the last, Mew, is number 151. Alternate forms that result in type changes and Mega Evolutions (introduced later in Generation 6) are included for convenience.National League (division)
The National League, currently named the Vanarama National League for sponsorship reasons, is the highest level of the National League System and fifth-highest of the overall English football league system. While all of the clubs in the top four divisions of English football are professional, the National League has a mixture of professional and semi-professional clubs. The National League is the lowest division in the English football pyramid organised on a nationwide basis. Formerly the Conference National, the league was renamed the National League from the 2015–16 season.Nile
The Nile (Arabic: النيل, written as al-Nīl; pronounced as an-Nīl) is a major north-flowing river in northeastern Africa, and is the longest river in Africa and in the world, though some sources cite the Amazon River as the longest. The Nile, which is about 6,650 km (4,130 mi) long, is an "international" river as its drainage basin covers eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Republic of the Sudan and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan.The river Nile has two major tributaries, the White Nile and Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself. The Blue Nile, however, is the source of most of the water and silt. The White Nile is longer and rises in the Great Lakes region of central Africa, with the most distant source still undetermined but located in either Rwanda or Burundi. It flows north through Tanzania, Lake Victoria, Uganda and South Sudan. The Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast. The two rivers meet just north of the Sudanese capital of Khartoum.The northern section of the river flows north almost entirely through the Sudanese desert to Egypt, then ends in a large delta and flows into the Mediterranean Sea. Egyptian civilization and Sudanese kingdoms have depended on the river since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of Aswan, and nearly all the cultural and historical sites of Ancient Egypt are found along river banks.One Piece
One Piece (Japanese: ワンピース, Hepburn: Wan Pīsu) is a Japanese manga series written and illustrated by Eiichiro Oda. It has been serialized in Shueisha's Weekly Shōnen Jump magazine since July 22, 1997, and has been collected into 92 tankōbon volumes. The story follows the adventures of Monkey D. Luffy, a boy whose body gained the properties of rubber after unintentionally eating a Devil Fruit. With his crew of pirates, named the Straw Hat Pirates, Luffy explores the Grand Line in search of the world's ultimate treasure known as "One Piece" in order to become the next Pirate King.
The manga spawned a media franchise, having been adapted into an original video animation (OVA) produced by Production I.G in 1998, and an anime series produced by Toei Animation, which began broadcasting in Japan in 1999. Additionally, Toei has developed thirteen animated feature films, one OVA and thirteen television specials. Several companies have developed various types of merchandising and media, such as a trading card game and numerous video games. The manga series was licensed for an English language release in North America and the United Kingdom by Viz Media and in Australia by Madman Entertainment. The anime series was licensed by 4Kids Entertainment for an English-language release in North America in 2004, before the license was dropped and subsequently acquired by Funimation in 2007.
One Piece has received praise for its storytelling, art, characterization, and humor. Several volumes of the manga have broken publishing records, including the highest initial print run of any book in Japan. The official website for Eiichiro Oda's One Piece manga announced that the manga has set a Guinness World Record for "the most copies published for the same comic book series by a single author". As of March 2019, the manga has sold over 450 million copies worldwide, making it the best-selling manga series in history. It became the best-selling manga for the eleventh consecutive year in 2018. One Piece is one of the highest-grossing media franchises of all time, estimated to have generated over $20 billion in total franchise revenue, from the manga, anime, films, games and merchandise.Quartz
Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at 573 °C (846 K). Since the transformation is accompanied by a significant change in volume, it can easily induce fracturing of ceramics or rocks passing through this temperature threshold.
There are many different varieties of quartz, several of which are semi-precious gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia.Red states and blue states
Since the 2000 United States presidential election, red states and blue states have referred to states of the United States whose voters predominantly choose either the Republican Party (red) or Democratic Party (blue) presidential candidates. Since then, the use of the term has been expanded to differentiate between states being perceived as liberal and those perceived as conservative. Examining patterns within states reveals that the reversal of the two parties' geographic bases has happened at the state level, but it is more complicated locally, with urban/rural divides associated with many of the largest changes.All states contain both liberal and conservative voters (i.e. they are "purple") and only appear blue/red on the electoral map because of the winner-take-all system used by most states in the Electoral College. However, the perception of some states as "blue" and some as "red" was reinforced by a degree of partisan stability from election to election—from the 2000 election to the 2004 election, only three states changed "color" and as of 2016 fully 38 out of 50 states have voted for the same party in every presidential election since the red/blue terminology was popularized in 2000.Toronto Blue Jays
The Toronto Blue Jays are a Canadian professional baseball team based in Toronto, Ontario. The Blue Jays compete in Major League Baseball (MLB) as a member club of the American League (AL) East division. The team plays its home games at the Rogers Centre.
The "Blue Jays" name originates from the bird of the same name, and blue is also the traditional colour of two of Toronto's other professional sports teams: the Maple Leafs (ice hockey) and the Argonauts (Canadian football). In addition, the team was originally owned by the Labatt Brewing Company, makers of the popular beer Labatt's Blue. Colloquially nicknamed the "Jays", the team's official colours are royal blue, navy blue, red, and white. An expansion franchise, the club was founded in Toronto in 1977. Originally based at Exhibition Stadium, the team began playing its home games at the SkyDome upon its opening in 1989. Since 2000, the Blue Jays have been owned by Rogers Communications and in 2004, the SkyDome was purchased by that company, which renamed it Rogers Centre. They are the second MLB franchise to be based outside the United States, and currently the only team based outside the U.S. after the first Canadian franchise, the Montreal Expos, became the Washington Nationals in 2005.
In the late 1970s and early 1980s, the Blue Jays went through struggles typical of an expansion team, frequently finishing in last place in its division. In 1983, the team had its first winning season and two years later, they became division champions. From 1985 to 1993, they were an AL East powerhouse, winning five division championships in nine seasons, including three consecutive from 1991 to 1993. During that run, the team also became back-to-back World Series champions in 1992 and 1993, led by a core group of award-winning All-Star players, including Hall of Famer Roberto Alomar, Joe Carter, John Olerud, and Devon White. The Blue Jays became the first (and, to date, only) team outside the US to appear in and win a World Series, and the fastest AL expansion team to do so, winning in its 16th year. After 1993, the Blue Jays failed to qualify for the playoffs for 21 consecutive seasons, until clinching a playoff berth and division championship in 2015. The team clinched a second consecutive playoff berth in 2016, after securing an AL wild card position. Both years, the Jays won the AL Division Series but lost the AL Championship Series.
The Blue Jays are one of two MLB teams under corporate ownership, with the other being the Atlanta Braves (who are owned by Liberty Media).
