Orange (colour)

Orangeis thecolourbetweenyellowandredon the spectrum ofvisible light. Thehuman eyesperceive orange when observing light with adominant wavelengthbetween roughly 585 and 620nanometres. In traditionalcolour theory, it is asecondary colourof pigments, produced by mixing yellow and red. In theRGB colour model, it is atertiary colour. It is named after thefruit of the same name.
The orange colour of many fruits and vegetables, such ascarrots,pumpkins,sweet potatoes, andoranges, comes fromcarotenes, a type ofphotosynthetic pigment. These pigments convert the light energy that the plants absorb from the Sun into chemical energy for the plants' growth. Similarly, the hues of autumn leaves are from the same pigment afterchlorophyllis removed.
In Europe and the United States, surveys show that orange is the colour most associated with amusement, the unconventional, extroversion, warmth, fire, energy, activity, danger, taste and aroma, theautumnandAllhallowtideseasons, as well as having long been thenational colourof the Netherlands and theHouse of Orange. It also serves as thepolitical colourof theChristian democracypolitical ideology and most Christian democratic political parties.In Asia, it is an important symbolic colour in Buddhism and Hinduism.
In English, the colour orange is named after the appearance of the ripeorange fruit.The word comes from theOld French:orange, from the old term for the fruit,pomme d'orange. The French word, in turn, comes from the Italianarancia,based on Arabicنارنج(nāranj), borrowed fromPersianنارنگ(nārang), derived fromSanskritनारङ्ग(nāraṅga), which in turn derives from aDravidianroot word (compareநரந்தம்/നാരങ്ങnārandam/nārañjawhich refers tobitter orangeinTamilandMalayalam).The earliest known recorded use oforangeas a colour name in English was in 1502, in a description of clothing purchased forMargaret Tudor.Another early recorded use was in 1512,in awillnow filed with thePublic Record Office. By the 17th century, the fruit and its colour were familiar enough that 'orange-coloured' shifted in use to 'orange' as an adjective.The place name "Orange" has a separateetymologyand is not related to that of the colour.
Before this word was introduced to the English-speaking world,saffronalready existed in the English language.Crogalso referred to the saffron colour, so that orange was also referred to asġeolurēad(yellow-red) for reddish orange, orġeolucrog(yellow-saffron) for yellowish orange.Alternatively, orange things were sometimes described as red (which then had a broader meaning)such asred deer,red hair,the Red Planetandrobin redbreast. When orange was infrequently used inheraldry, it was referred to astawnyorbrusk.
Inancient Egypt, andancient India, artists used an orange colour on some of their items. In Egypt, a mineral pigment calledrealgarwas used for tomb paintings, as well as for other purposes. Orangecarnelianswere significantly used during theIndus Valley Civilisationwhich was, in turn, obtained by the people ofKutch,Gujarat, India.The colour was also used later by medieval artists for the colouring of manuscripts. Pigments were also made in ancient times from a mineral known asorpiment. Orpiment was an important item of trade in theRoman Empireand was used as a medicine inancient Chinaalthough it containsarsenicand is highly toxic. It was also used as a fly poison and to poison arrows. Because of its yellow-orange colour, it was also a favourite with alchemists who were searching for a way to make gold, both in China and in the West.
Before the late 15th century, the colour orange existed in Europe, but without the name; it was simply called yellow-red. Portuguese merchants brought the first orange trees to Europe from Asia in the late 15th and early 16th century, along with the Sanskrit wordnāraṅga, which gradually became part of severalEuropean languages:naranjain Spanish,laranjain Portuguese, andorangein English & French. In mid-16th century England, the colour referred to as 'orange' was a reddish-brown, matching the deteriorated appearance of the fruit after a long journey from where it was grown in Portugal or |Spain Improvements in transportation and the introduction of an orange grove inSurreyallowed the fresh fruit to become more familiar in England, and the colour referred to asorangeshifted in the 17th century toward its modern understanding.
TheHouse of Orange-Nassauwas one of the most influential royal houses in Europe in the 16th and 17th centuries. It originated in 1163 in the tinyPrincipality of Orange, a feudal state of 108 square miles (280 km) north ofAvignonin southern France. The Principality of Orange took its name not from the fruit, but from a Roman-Celtic settlement on the site which was founded in 36 or 35 BC and was named after the Celtic water godArausio;however, the name may have been slightly altered, and the town associated with the colour, because it was on the route by which quantities of oranges were brought from southern ports such asMarseilleto northern France.
The family of the Prince of Orange eventually adopted the name and the colour orange in the 1570s.The colour came to be associated with Protestantism, due to participation by the House of Orange on the Protestant side in theFrench Wars of Religion. One member of the house,William I of Orange, organised theEighty Years' Warcomprising resistance against Spain, a war that lasted eighty years, until the Netherlands won its independence. The House's arguably most prominent member,William III of Orange, becameKing of Englandin 1689, after the downfall of the CatholicJames IIin theGlorious Revolution.
Due toWilliam III, orange became an important political colour in Britain and Europe. William was a Protestant, and as such, he defended theProtestant minority of Irelandagainst the majorityRoman Catholicpopulation. As a result, the Protestants of Ireland were known asOrangemen. Orange eventually became one of the colours of theIrish flag, symbolising the Protestant heritage. His orange-white-and-blue rebel flag became the forerunner of The Netherlands' modern flag.
When theDutch settlersliving in theCape Colony(now part ofSouth Africa)migrated into the Southern African heartlandsin the 19th century, they founded what they called theOrange Free State. In theUnited States, the flag ofNew York Cityhas an orange stripe, to remember the Dutch colonists who founded the city. William of Orange is also remembered as the founder of theCollege of William & Mary, andNassau County, New Yorkis named after the House of Orange-Nassau.
In the 18th century, orange was sometimes used to depict the robes ofPomona, the goddess of fruitful abundance; her name came from thepomon, the Latin word for fruit. Oranges themselves became more common in northern Europe, thanks to the 17th-century invention of the heated greenhouse, a building type which became known as anorangerie. The French artistJean-Honoré Fragonarddepicted an allegorical figure of inspiration dressed in orange.
In 1797 a French scientistLouis Vauquelindiscovered the mineralcrocoite, orlead chromate, which led in 1809 to the invention of the synthetic pigmentchrome orange. Other synthetic pigments,cobalt red,cobalt yellow, and cobalt orange, the last made fromcadmium sulfidepluscadmium selenide, soon followed. These new pigments, plus the invention of themetal paint tubein 1841, made it possible for artists to paint outdoors and to capture the colours of natural light.
In Britain, orange became highly popular with thePre-Raphaelitesand with history painters. The flowing red-orange hair ofElizabeth Siddal, a prolific model and the wife of painterDante Gabriel Rossetti, became a symbol of thePre-Raphaelite movement.Lord Leighton, the president of the Royal Academy, producedFlaming June, a painting of a sleeping young woman in a bright orange dress, which won wide acclaim.Albert Joseph Moorepainted festive scenes ofRomanswearing orange cloaks brighter than any of the Romans ever likely wore. In the United States,Winslow Homerbrightened his palette with vivid oranges.
In France, painters took orange in an entirely different direction. In 1872Claude MonetpaintedImpression, Sunrise, a tiny orange sun and some orange light reflected on the clouds and water in the centre of a hazy blue landscape. This painting gave its name to theImpressionistmovement.
Orange became an important colour for all the Impressionist painters. They all had studied the recent books on colour theory, and they know that orange placed next to azure blue made both colours much brighter.Auguste Renoirpainted boats with stripes of chrome orange paint straight from the tube.Paul Cézannedid not use orange pigment, but produced his own oranges with touches of yellow, red and ochre against a blue background.Toulouse-Lautrecoften used oranges in the skirts of dancers and gowns of Parisiennes in the cafes and clubs he portrayed. For him, it was the colour of festivity and amusement.
The Post-Impressionists went even further with orange.Paul Gauguinused oranges as backgrounds, for clothing and skin colour, to fill his pictures with light and exoticism. But no other painter used orange so often and dramatically asVincent van Gogh. who had shared a house with Gauguin inArlesfor a time. For Van Gogh orange and yellow were the pure sunlight of Provence. He produced his own oranges with mixtures of yellow, ochre and red, and placed them next to slashes of sienna red and bottle green, and below a sky of turbulent blue and violet. He put an orange moon and stars in a cobalt blue sky. He wrote to his brother Theo of searching for oppositions of blue with orange, of red with green, of yellow with violet, searching for broken colours and neutral colours to harmonize the brutality of extremes, trying to make the colours intense, and not a harmony of greys.
In the 20th and 21st centuries, the colour orange had highly varied associations, both positive and negative.
The high visibility of orange made it a popular colour for certain kinds of clothing and equipment. DuringWorld War II, US Navy pilots in the Pacific began to wear orange inflatable life jackets, which could be spotted by search and rescue planes. After the war, these jackets became common on both civilian and naval vessels of all sizes, and on aircraft flown over water. Orange is also widely worn (to avoid being hit) by workers on highways and by cyclists.
AherbicidecalledAgent Orangewas widely sprayed from aircraft by theRoyal Air Forceduring theMalayan Emergencyand theUS Air Forceduring theVietnam Warto remove the forest and jungle cover beneath which enemy combatants were believed to be hiding, and to expose their supply routes. The chemical was not actually orange, but took its name from the colour of the steel drums in which it was stored. Agent Orange was toxic, and was later linked to birth defects and other health problems.
Orange also had and continues to have a political dimension. Orange serves as the colour ofChristian democraticpolitical ideology, which is based onCatholic social teachingandNeo-Calvinisttheology; Christian democratic political parties came to prominence in Europe and the Americas after World War II.
In Ukraine in November–December 2004, it became the colour of theOrange Revolution, a popular movement which carried activist and reformerViktor Yushchenkointo the presidency.In parts of the world, especiallyNorthern Ireland, the colour is associated with theOrange Order, aProtestantfraternal organisation and relatedly, Orangemen, marches and other social and political activities, with the colour orange being associated with Protestantism similar to the Netherlands.
Inoptics, orange is the colour seen by the eye when looking at light with a wavelength between approximately 585–620nm. It has ahueof 30° inHSV colour space. Isaac Newton'sOpticksdistinguished between pure orange light and mixtures of red and yellow light by noting that mixtures could be separated using a prism.
In the traditional colour wheel used by painters, orange is the range of colours between red and yellow, and painters can obtain orange simply by mixing red and yellow in various proportions; however these colours are never as vivid as a pure orange pigment. In theRGB colour model(the system used to display colours on a television or computer screen), orange is generated by combining high intensity red light with a lower intensity green light, with the blue light turned off entirely. Orange is atertiary colourwhich is numerically halfway betweengamma-compressedred and yellow, as can be seen in theRGB colour wheel.
Regarding painting, blue is the complementary colour to orange. As many painters of the 19th century discovered, blue and orange reinforce each other. The painter Vincent van Gogh wrote to his brother Theo that in his paintings, he was trying to reveal "the oppositions of blue with orange, of red with green, of yellow with violet... trying to make the colours intense and not a harmony of grey".In another letter he wrote simply, "There is no orange without blue."Van Gogh,Pierre-Auguste Renoirand many otherImpressionistandPost-Impressionistpainters frequently placed orange against azure or cobalt blue, to make both colours appear brighter.
The actual complement of orange isazure– a colour that is one quarter of the way between blue and green on the colour spectrum. The actual complementary colour of true blue is yellow. Orange pigments are largely in theochreorcadmiumfamilies, and absorb mostly greenish-blue light.
Other orange pigments include:
The orange colour ofcarrots,pumpkins,sweet potatoes,oranges, and many other fruits and vegetables comes fromcarotenes, a type ofphotosynthetic pigment. These pigments convert the light energy that the plants absorb from the sun into chemical energy for the plants' growth. The carotenes themselves take their name from the carrot.Autumn leavesalso get their orange colour from carotenes. When the weather turns cold and production of greenchlorophyllstops, the orange colour remains.
Before the 18th century, carrots from Asia were usually purple, while those in Europe were either white or red. Dutch farmers bred a variety that was orange; according to some sources, as a tribute to thestadtholderofHollandandZeeland,William of Orange.The long orange Dutch carrot, first described in 1721, is the ancestor of the orange horn carrot, one of the most common types found in supermarkets today. It takes its name from the town ofHoorn, in the Netherlands.
Orange is traditionally associated with theautumnseason, with the harvest and autumn leaves. The flowers, like orange fruits and vegetables and autumn leaves, get their colour from the photosynthetic pigments calledcarotenes.
Orange is a very common colour of fruits, vegetables, spices, and other foods in many different cultures. As a result, orange is the colour most often associated in western culture with taste and aroma.Orange foods include peaches,apricots,mangoes,carrots,shrimp,salmon roe, and many other foods. Orange colour is provided byspicessuch aspaprika,saffronandcurry powder. In the United States, withHalloweenon 31 October, and in North America withThanksgivingin October (Canada) and November (US) orange is associated with the harvest colour, and also is the colour of the carved pumpkins, or jack-o-lanterns, used to celebrate the holiday.
People associate certain colours with certainflavours, and the colour of food can influence the perceived flavour in anything fromcandytowine.Since orange is popularly associated with good flavour, many companies add orangefood colouringto improve the appearance of their packaged foods. Orange pigments and dyes, synthetic or natural, are added to many orange sodas and juices, cheeses (particularlycheddar cheese,Gloucester cheese, andAmerican cheese); snack foods, butter and margarine; breakfast cereals, ice cream,yoghurt, jam and candy. It is also often added to children's medicine, and tochicken feedto make theegg yolksmore orange.
The United States Government and theEuropean Unioncertify a small number of synthetic chemical colourings to be used in food. These are usuallyaromatic hydrocarbons, orazo dyes, made from petroleum. The most common ones are:
Because many consumers are worried about possible health consequences of synthetic dyes, some companies are beginning to use natural food colours. Since these food colours are natural, they do not require any certification from the Food and Drug Administration. The most popular natural food colours are:
In Confucianism, the religion and philosophy of ancient China, orange was the colour of transformation. In China and India, the colour took its name not from the orange fruit, but from saffron, the finest and most expensive dye in Asia. According to Confucianism, existence was governed by the interaction of the male active principle, theyang, and the female passive principle, theyin. Yellow was the colour of perfection and nobility; red was the colour of happiness and power. Yellow and red were compared to light and fire, spirituality and sensuality, seemingly opposite but really complementary. Out of the interaction between the two came orange, the colour of transformation.
A wide variety of colours, ranging from a slightly orange yellow to a deep orange red, all simply calledsaffron, are closely associated with Hinduism and Buddhism, and are commonly worn by monks and holy men across Asia.
In Hinduism, the divinityKrishnais commonly portrayed dressed in yellow or yellow orange. Yellow and saffron are also the colours worn bysadhu, or wandering pious men in India.
In Buddhism, orange (or more precisely saffron) was the colour of illumination, the highest state of perfection.The saffron colours of robes to be worn by monks were defined by the Buddhist texts. The robe and its colour is a sign of renunciation of the outside world and commitment to the order. The candidate monk, with his master, first appears before the monks of the monastery in his own clothes, with his new robe under his arm and asks to enter the order. He then takes his vows, puts on the robes, and with his begging bowl, goes out to the world. Thereafter, he spends his mornings begging and his afternoons in contemplation and study, either in a forest, garden, or in the monastery.
According to Buddhist scriptures and commentaries, the robe dye is allowed to be obtained from six kinds of substances: roots and tubers, plants, bark, leaves, flowers and fruits. The robes should also be boiled in water for a long time to get the correctly sober colour. Saffron and ochre, usually made with dye from thecurcuma longaplant or the heartwood of thejackfruittree, are the most common colours. The so-called forest monks usually wear ochre robes and city monks saffron, though this is not an official rule.
The colour of robes also varies somewhat among the differentvehicles(schools) of Buddhism, and by country, depending on their doctrines and the dyes available. The monks of the strictVajrayana, orTantric Buddhism, practised in Tibet, wear the most colourful robes of saffron and red. The monks ofMahayana Buddhism, practised mainly in Japan, China and Korea, wear lighter yellow or saffron, often with white or black. Monks ofTheravada Buddhism, practised in Southeast Asia, usually wear ochre or saffron colour. Monks of the forest tradition in Thailand and other parts of Southeast Asia wear robes of a brownish ochre, dyed from the wood of thejackfruittree.
In Europe and America orange and yellow are the colours most associated with amusement, frivolity and entertainment. In this regard, orange is the exact opposite of its complementary colour, blue, the colour of calm and reflection. Mythological paintings traditionally showedBacchus(known inGreek mythologyasDionysus), the god of wine, ritual madness and ecstasy, dressed in orange. Clowns have long worn orange wigs.Toulouse-Lautrecused a palette of yellow, black and orange in his posters of Paris cafes and theatres, andHenri Matisseused an orange, yellow and red palette in his painting, theJoy of Living.
Orange is the colour most easily seen in dim light or against the water, making it, particularly the shade known assafety orange, the colour of choice for life rafts, life jackets orbuoys. Highway temporary signs about construction or detours in the United States are orange, because of its visibility and its association with danger.
It is worn by people wanting to be seen, including highway workers and lifeguards. Prisoners are also sometimes dressed in orange clothing to make them easier to see during an escape. Lifeguards on the beaches ofLos Angeles County, both real and in television series, wear orange swimsuits to make them stand out. Orange astronaut suits have the highest visibility in space, or against blue sea. An aircraft's two types of "black box", orflight data recorderandcockpit voice recorder, are actually bright orange, so they can be found more easily. In some cars,connectorsrelated to safety systems, such as the airbag, may be coloured orange.
TheGolden Gate Bridgeat the entrance ofSan Francisco Bayis paintedinternational orangeto make it more visible in the fog. Next to red, it is the colour most popular for extroverts, and as a symbol of activity.
Orange is sometimes used, like red and yellow, as a colour warning of possible danger or calling for caution. A skull against an orange background means a toxic substance or poison.
In the colour system devised by the USDepartment of Homeland Securityto measure the threat of terrorist attack, an orange level is second only to a red level. The USManual on Uniform Traffic Control Devicesspecifies orange for use in temporary and construction signage.
Because of its symbolic meaning as the orange colour of activity, orange is often used as the colour of political and social movements.
In theUnited States Army, orange has traditionally been associated with thedragoons, the mounted infantry units which eventually became theUS Cavalry. The1st Cavalry Regimentwas founded in 1833 as the United States Dragoons. The modern coat of arms of the 1st Cavalry features the colour orange and orange-yellow shade called dragoon yellow, the colours of the early US dragoon regiments.TheUS Signal Corps, founded at the beginning of theAmerican Civil War, adopted orange and white as its official colours in 1872. Orange was adopted because it was the colour of a signal fire, historically used at night while smoke was used during the day, to communicate with distant army units.
Prior to and during theNapoleonic Warsa pale shade of orange known asaurore("dawn") was adopted as thefacing colourof several cavalry regiments in the French army. The colour resembled that of the early rising sun.
In theRoyal Netherlands Air Force, aircraft may have aroundelwith an orange dot in the middle, surrounded by three circular sectors in red, white, and blue.
In theIndonesian Air Force, theAir force infantryand special forces corps known asPaskhasuses Orange as theirberetcolour.
