'''White''' is an [[achromatic color]], literally a "color without color", composed of a mixture of frequencies of the light of the [[visible spectrum]]. It is one of the most common colors in nature, the color of [[sunlight]], [[snow]], [[milk]], [[chalk]], [[limestone]] and other common minerals. In many cultures white represents or signifies purity, innocence, and light, and is the symbolic opposite of [[black]], or darkness.

White is an achromatic color, literally a "color without color", composed of a mixture of frequencies of the light of the visible spectrum. It is one of the most common colors in nature, the color of sunlight, snow, milk, chalk, limestone and other common minerals. In many cultures white represents or signifies purity, innocence, and light, and is the symbolic opposite of black, or darkness. According to surveys in Europe and the United States, white is the color most often associated with perfection, the good, honesty, cleanliness, the beginning, the new, neutrality, and exactitude.[1]
In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore a white toga as a symbol of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity; the widows of Kings dressed in white rather than black as the color of mourning. It sometimes symbolizes royalty; it was the color of monarchism after the French Revolution and of the White Russians who fought the Bolsheviks during the Russian Civil War. Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches, capitols and other government buildings. It was also widely used in 20th century modern architecture as a symbol of modernity, simplicity and strength.
White is an important color for almost all world religions. The Pope, the head of the Roman Catholic Church, has worn white since 1566, as a symbol of purity and sacrifice. In Islam, and in the Shinto religion of Japan, it is worn by pilgrims; and by the Brahmins in India, In Western cultures and in Japan, white is the most common color for wedding dresses, symbolizing purity and virginity.
The white color on television screens and computer monitors is created with the RGB color model by mixing red, green and blue light at equal intensities.
In nature, snow and clouds appear white because they are composed of water droplets or ice crystals mixed with air; when white sunlight enters snow, very little of the spectrum is absorbed; almost all of the light is reflected or scattered by the air and water molecules, so the snow appears to be the color of sunlight, white.[2] Beaches with sand containing high amounts of quartz or eroded limestone also appear white, since quartz and limestone reflect or scatter sunlight, rather than absorbing it. Tropical white sand beaches may also have a high quantity of white calcium carbonate from tiny bits of seashells ground to fine sand by the action of the waves.[3]

Etymology
The word white continues Old English hwīt, ultimately from a Common Germanic *χwītaz also reflected in OHG (h)wîz, ON hvítr, Goth. ƕeits. The root is ultimately from Proto-Indo-European language *kwid-, surviving also in Sanskrit śveta "to be white or bright"[4] and Slavonic světŭ "light".[5][6] The Icelandic word for white, hvítur, is directly derived from the Old Norse form of the word hvítr. Common Germanic also had the word *blankaz ("white, bright, blinding"), borrowed into Late Latin as *blancus, which provided the source for Romance words for "white" (Catalan, Occitan and French blanc, Spanish blanco, Italian bianco, Galician-Portuguese branco, etc.). The antonym of white is black.
Some non-European languages have a wide variety of terms for white. The Inuit language has seven different words. Sanskrit has specific words for bright white, the white of teeth, the white of sandalwood, the white of the autumn moon, the white of silver, the white of cow's milk, the white of pearls, the white of a ray of sunlight, and the white of stars. Japanese has six different words, depending upon brilliance or dullness, or if the color is inert or dynamic.[7]
White in history and art
The Ancient World
White was one of the first colors used by paleolithic artists; they used calcite or chalk,[8] sometimes as a background, sometimes as a highlight, along with charcoal and red and yellow ochre in their vivid cave paintings.[9]
In ancient Egypt, white was connected with the goddess Isis. The priests and priestesses of Isis dressed only in white linen, and it was used to wrap mummies.[10]
In Greece and other ancient civilizations, white was often associated with mother's milk. In Greek mythology, the god Zeus was nourished at the breast of the nymph Amalthea. In the Talmud, milk was one of four sacred substances, along with wine, honey, and the rose.[11]
The ancient Greeks saw the world in terms of darkness and light, so white was a fundamental color. According to Pliny the Elder in his Natural History, Apelles (4th century BC) and the other famous painters of ancient Greece used only four colors in their paintings; white, red, yellow and black;[12] For painting, the Greeks used lead white, made by a long and laborious process.
A plain white toga, known as a toga virilis, was worn for ceremonial occasions by all Roman citizens over the age of 14–18. Magistrates and certain priests wore a toga praetexta, with a broad purple stripe. In the time of the Emperor Augustus, no Roman man was allowed to appear in the Roman forum without a toga.
The ancient Romans had two words for white; albus, a plain white, (the source of the word albino); and candidus, a brighter white. A man who wanted public office in Rome wore a white toga brightened with chalk, called a toga candida, the origin of the word candidate. The Latin word candere meant to shine, to be bright. It was the origin of the words candle and candid.[13]
In ancient Rome, the priestesses of the goddess Vesta dressed in white linen robes, a white palla or shawl, and a white veil. They protected the sacred fire and the penates of Rome. White symbolized their purity, loyalty, and chastity.[10]

The Middle Ages and the Renaissance
The early Christian church adopted the Roman symbolism of white as the color of purity, sacrifice and virtue. It became the color worn by priests during mass, the color worn by monks of the Cistercian Order, and, under Pope Pius V, a former monk of the Dominican Order, it became the official color worn by the Pope himself. Monks of the order of Saint Benedict dressed in the white or gray of natural undyed wool, but later changed to black, the color of humility and penitence.
In Medieval art, the white lamb became the symbol of the sacrifice of Christ on behalf of mankind. John the Baptist described Christ as the lamb of God, who took the sins of the world upon himself. The white lamb was the center of one of the most famous paintings of the Medieval period, the Ghent Altarpiece by Jan van Eyck.[14]
White was also the symbolic color of the transfiguration. The Gospel of Saint Mark describes Jesus' clothing in this event as "shining, exceeding white as snow." Artists such as Fra Angelico used their greatest skill to capture the whiteness of his garments. In his painting of the transfiguration at the Convent of Saint Mark in Florence, Fra Angelico emphasized the white garment by using a light gold background, placed in an almond-shaped halo.[15]
The white unicorn was a common subject of Medieval and Renaissance manuscripts, paintings and tapestries. It was a symbol of purity, chastity and grace, which could only be captured by a virgin. It was often portrayed in the lap of the Virgin Mary.[16]
During the Middle Ages, painters rarely ever mixed colors; but in the Renaissance, the influential humanist and scholar Leon Battista Alberti encouraged artists to add white to their colors to make them lighter, brighter, and to add hilaritas, or gaiety. Many painters followed his advice, and the palette of the Renaissance was considerably brighter.[17]
In the Middle Ages and Renaissance, white was commonly worn by widows as a color of mourning. The widows of the Kings of France wore white until Anne of Brittany in the 16th century. A white tunic was also worn by many knights, along with a red cloak, which showed the knights were willing to give their blood for the King or Church.

Eighteenth and nineteenth centuries
White was the dominant color of architectural interiors in the Baroque period and especially the Rococo style that followed it in the 18th century. Church interiors were designed to show the power, glory and wealth of the church. They seemed to be alive, filled with curves, asymmetry, mirrors, gilding, statuary and reliefs, unified by white.
White was also a fashionable color for both men and women in the 18th century. Men in the aristocracy and upper classes wore powdered white wigs and white stockings, and women wore elaborate embroidered white and pastel gowns.
After the French Revolution, under Napoleon Bonaparte, a more austere white became the most fashionable color in women's costumes. The Empire style was modeled after the dress of Ancient Rome. The dresses were high in fashion but low in warmth; some women, including the Empress Joséphine de Beauharnais, died from illnesses caught wearing the thin garments in cold weather.
White was the universal color of both men and women's underwear and of sheets in the 18th and 19th century. It was unthinkable to have sheets or underwear of any other color. The reason was simple; the manner of washing linen in boiling water caused colors to fade. When linen was worn out, it was collected and turned into high-quality paper.[18]
The 19th-century American painter James McNeill Whistler (1834–1903), working at the same time as the French impressionists, created a series of paintings with musical titles where he used color to create moods, the way composers used music. His painting "Symphony in White No. 1 - The White Girl", which used his mistress Joanna Hiffernan as a model, used delicate colors to portray innocence and fragility, and a moment of uncertainty.[19]

Twentieth and twenty-first centuries
The White movement was the opposition that formed against the Bolsheviks during the Russian Civil War, which followed the Russian Revolution in 1917. It was finally defeated by the Bolsheviks in 1921-22, and many of its members emigrated to Europe.
At the end of the nineteenth century, lead white was still the most popular pigment; but between 1916 and 1918, chemical companies in Norway and the United States began to produce titanium white, made from titanium oxide. It had first been identified in the 18th century by the German chemist Martin Klaproth, who also discovered uranium. It had twice the covering power of lead white, and was the brightest white pigment known. By 1945, 80 percent of the white pigments sold were titanium white.[20]
The absoluteness of white appealed to modernist painters. It was used in its simplest form by the Russian suprematist painter Kazimir Malevich in his 1917 painting 'the white square,' the companion to his earlier 'black square.' It was also used by the Dutch modernist painter Piet Mondrian. His most famous paintings consisted of a pure white canvas with grid of vertical and horizontal black lines and rectangles of primary colors.
Black and white also appealed to modernist architects, such as Le Corbusier (1887–1965). He said a house was "a machine for living in" and called for a "calm and powerful architecture" built of reinforced concrete and steel, without any ornament or frills.[21] Almost all the buildings of contemporary architect Richard Meier, such as his museum in Rome to house the ancient Roman Ara Pacis, or Altar of Peace, are stark white, in the tradition of Le Corbusier.

Science
Optics and white light
White is the color the human visual system senses when the incoming light to the eye stimulates all three types of color sensitive cone cells in the eye in nearly equal amounts.[22] Materials that do not emit light themselves appear white if their surfaces reflect back most of the light that strikes them in a diffuse way.
The International Commission on Illumination defines white (adapted) as "a color stimulus that an observer who is adapted to the viewing environment would judge to be perfectly achromatic and to have a luminance factor of unity. The color stimulus that is considered to be the adapted white may be different at different locations within a scene.[23]
The adaptation mentioned in the CIE definition above is the chromatic adaptation by which the same colored object in a scene experienced under very different illuminations will be perceived as having nearly the same color. The same principle is used in photography and cinematography where the choice of white point determines a transformation of all other color stimuli. Changes in or manipulation of the white point can be used to explain some optical illusions such as The dress.
Before Isaac Newton, most scientists believed that white was the fundamental color of light. Newton demonstrated that this was not true by passing white light through a prism, breaking it up into its composite colors, and then using a second prism to reassemble them.
White light can be generated by the sun, by stars, or by earthbound sources such as fluorescent lamps, white LEDs and Incandescent bulbs. On the screen of a color television or computer, white is produced by mixing the primary colors of light: red, green and blue (RGB) at full intensity, a process called additive mixing (see image below). White light can be fabricated using light with only two wavelengths, for instance by mixing light from a red and cyan laser or yellow and blue lasers. This light will however have very few practical applications since color rendering of objects will be greatly distorted. The fact that light sources with vastly different spectral power distributions can result in a similar sensory experience is due to the way the light is processed by the visual system. One color that arise from two different spectral power distributions is called a metamerism.
-
In the RGB color model, used to create colors on TV and computer screens, white is made by mixing red, blue and green light at full intensity.
Many of the light sources that emit white light emit light at almost all visible wavelengths (sun light, incandescent lamps of various Color temperatures). This has led to the notion that white light can be defined as a mixture of "all colors" or "all visible wavelengths". This misconception is widespread [24][25][26] and might originally stem from the fact that Newton discovered that sunlight is composed of light with wavelengths across the visible spectrum. Concluding that since "all colors" produce white light then white must be made up of "all colors" is a common logical error called affirming the consequent, which might be the cause of the misunderstanding.
Why snow, clouds and beaches are white
Snow is a mixture of air and tiny ice crystals. When white sunlight enters snow, very little of the spectrum is absorbed; almost all of the light is reflected or scattered by the air and water molecules, so the snow appears to be the color of sunlight, white. Sometimes the light bounces around inside the ice crystals before being scattered, making the snow seem to sparkle.[2]
In the case of glaciers, the ice is more tightly pressed together and contains little air. As sunlight enters the ice, more light of the red spectrum is absorbed, so the light scattered will be bluish.[27]
Clouds are white for the same reason as ice. They are composed of water droplets or ice crystals mixed with air, very little light that strikes them is absorbed, and most of the light is scattered, appearing to the eye as white. Shadows of other clouds above can make clouds look gray, and some clouds have their own shadow on the bottom of the cloud.[28]
Many mountains with winter or year-round snow cover are named accordingly: Mauna Kea means white mountain in Hawaiian, Mont Blanc means white mountain in French. Changbai Mountains literally meaning 'Perpetually White' Mountains, marks the border between China and Korea.
Beaches with sand containing high amounts of quartz or eroded limestone also appear white, since quartz and limestone reflect or scatter sunlight, rather than absorbing it. Tropical white sand beaches may also have a high quantity of white calcium carbonate from tiny bits of seashells ground to fine sand by the action of the waves.[3]

Pensacola Beach, Florida. White sand beaches look white because the quartz or eroded limestone in the sand reflects or scatters sunlight without absorbing other colors.
Chemistry- white pigments and dyes
Chalk is a kind of limestone, made of the mineral calcite, or calcium carbonate. It was originally deposited under the sea as the scales or plates of tiny micro-organisms called Coccolithophore. It was the first white pigment used by prehistoric artists in cave paintings. The chalk used on blackboards today is usually made of gypsum or calcium sulphate, a powder pressed into sticks.
Bianco di San Giovanni is a pigment used in the Renaissance, which was described by the painter Cennino Cennini in the 15th century. It is similar to chalk, made of calcium carbonate with calcium hydroxide. It was made of dried lime which was made into a powder, then soaked in water for eight days, with the water changed each day. It was then made into cakes and dried in the sun.[29]
Lead white was being produced during the 4th century BC; the process is described is Pliny the Elder, Vitruvius and the ancient Greek author Theophrastus. Pieces of lead were put into clay pots which had a separate compartment filled with vinegar. The pots in turn were piled on shelves close to cow dung. The combined fumes of the vinegar and the cow dung caused the lead to corrode into lead carbonate. It was a slow process which could take a month or more. It made an excellent white and was used by artists for centuries, but it was also toxic. It was replaced in the 19th century by zinc white and titanium white.[30]
Titanium white is the most popular white for artists today; it is the brightest available white pigment, and has twice the coverage of lead white. It first became commercially available in 1921. It is made out of titanium dioxide, from the minerals brookite, anatase, rutile, or Ilmenite, currently the major source. Because of its brilliant whiteness, it is used as a colorant for most toothpaste and sunscreen.[31]
Zinc white is made from zinc oxide. It is similar to but not as opaque as titanium white. It is added to some breakfast cereals, since zinc is an important nutrient.
Some materials can be made to look "whiter than white", this is achieved using optical brightener agents (OBA). These are chemical compounds that absorb light in the ultraviolet and violet region (usually 340-370 nm) of the electromagnetic spectrum, and re-emit light in the blue region (typically 420-470 nm). OBAs are often used in paper and clothing to create an impression of very bright white. This is due to the fact that the materials actually send out more visible light than they receive.
Chinese white is a variety of zinc white made for artists.

Bleach and bleaching
Bleaching is a process for whitening fabrics which has been practiced for thousands of years. Sometimes it was simply a matter of leaving the fabric in the sun, to be faded by the bright light. In the 18th century several scientists developed varieties of chlorine bleach, including sodium hypochlorite and calcium hypochlorite (bleaching powder).[32] Bleaching agents that do not contain chlorine most often are based on peroxides, such as hydrogen peroxide, sodium percarbonate and sodium perborate. While most bleaches are oxidizing agents, a fewer number are reducing agents such as sodium dithionite.
Bleaches attack the chromophores, the part of a molecule which absorbs light and causes fabrics to have different colors. An oxidizing bleach works by breaking the chemical bonds that make up the chromophore. This changes the molecule into a different substance that either does not contain a chromophore, or contains a chromophore that does not absorb visible light. A reducing bleach works by converting double bonds in the chromophore into single bonds. This eliminates the ability of the chromophore to absorb visible light.[33]
Sunlight acts as a bleach through a similar process. High energy photons of light, often in the violet or ultraviolet range, can disrupt the bonds in the chromophore, rendering the resulting substance colorless.[34]
Some detergents go one step further; they contain fluorescent chemicals which glow, making the fabric look literally whiter than white.[35]
Astronomy
A white dwarf is a stellar remnant composed mostly of electron-degenerate matter. They are very dense; a white dwarf's mass is comparable to that of the Sun and its volume is comparable to that of the Earth. Its faint luminosity comes from the emission of stored thermal energy.
A white dwarf is very hot when it is formed, but since it has no source of energy, it will gradually radiate away its energy and cool down. This means that its radiation, which initially has a high color temperature, will lessen and redden with time. Over a very long time, a white dwarf will cool to temperatures at which it will no longer emit significant heat or light, and it will become a cold black dwarf.[36] However, since no white dwarf can be older than the age of the Universe (approximately 13.8 billion years),[37] even the oldest white dwarfs still radiate at temperatures of a few thousand kelvins, and no black dwarfs are thought to exist yet.

Associations and symbolism
Innocence and sacrifice
In Western culture, white is the color most often associated with innocence.[39] In Biblical times, lambs and other white animals were sacrificed to expiate sins. In Christianity Christ is considered the "lamb of God," who died for the sins of mankind. The white lily is considered the flower of purity and innocence, and is often associated with the Virgin Mary.
The beginning and the new
White is the color in Western culture most often associated with beginnings and the new. In the Bible, light was created immediately after the heavens and the earth. In Christianity, children are baptized wearing white, and, wear white for their first communion. Christ after his Resurrection is traditionally portrayed dressed in white. Eggs, another symbol of the new, are used to celebrate Easter.
The Queen of the United Kingdom traditionally wears white when she opens the session of Parliament. In high society, debutantes traditionally wear white for their first ball. A new project is often described as beginning with a "blank page."
Weddings
White has long been the traditional color worn by brides at royal weddings, but the white wedding gown for ordinary people appeared in the 19th century. Before that time, most brides wore their best Sunday clothing, of whatever color.[40] The white lace wedding gown of Queen Victoria in 1840 had a large impact on the color and fashion of wedding dresses in both Europe and America down to the present day.
-
The wedding dress of Queen Victoria (1840) set the fashion for wedding dresses of the Victorian era and for the 20th century.
-
The wedding of Czar Nicholas II of Russia and Alexandra Feodorovna (Alix of Hesse), the granddaughter of Queen Victoria, in 1894.
-
The Barong Tagalog was a traditional Folk costume of the Philippines,this attire wear in the formal gatherings and weddings.
Cleanliness
White is the color most associated with cleanliness. Objects which are expected to be clean, such as refrigerators and dishes, toilets and sinks, bed linen and towels, are traditionally white. White was the traditional color of the coats of doctors, nurses, scientists and laboratory technicians, though nowadays a pale blue or green is often used. White is also the color most often worn by chefs, bakers, and butchers, and the color of the aprons of waiters in French restaurants.[41]
Ghosts, phantoms and the Four Horsemen of the Apocalypse
White is the color associated with ghosts and phantoms. In the past the dead were traditionally buried in a white shroud. Ghosts are said to be the spirits of the dead who, for various reasons, are unable to rest or enter heaven, and so walk the earth in their white shrouds. White is also connected with the paleness of death. A common expression in English is "pale as a ghost."[42]
The woman in white, Weiße Frau, or dame blanche is a familiar figure in English, German and French ghost stories. She is a spectral apparition of a female clad in white, in most cases the ghost of an ancestor, sometimes giving warning about death and disaster. The most notable Weiße Frau is the legendary ghost of the German Hohenzollern dynasty.
Seeing a white horse in a dream is said to be presentiment of death.[43] In the Book of Revelation, the last book in the New Testament of the BIble, the Four Horsemen of the Apocalypse are supposed to announce the Apocalypse before the Last Judgement. The man on a white horse with a bow and arrow. according to different interpretations, represents either War and Conquest, the Antichrist, or Christ himself, cleansing the world of sin. Death rides a horse whose color is described in ancient Greek as khlōros (χλωρός) in the original Koine Greek,[44] which can mean either green/greenish-yellow or pale/pallid.[45]

White in other cultures
In China, Korea, and some other Asian countries, white, or more precisely, the whitish color of undyed linen, is the color of mourning and funerals.[47]
In traditional China, undyed linen clothing is worn at funerals. As time passes, the bereaved can gradually wear clothing dyed with colors, then with darker colors. Small sacks of quicklime, one for each year of the life of the deceased are placed around the body to protect it against impurity in the next world, and white paper flowers are placed around the body.[48]
In China and other Asian counties, white is the color of reincarnation, showing that death is not a permanent separation from the world.[49]
In China, white is associated with the masculine (the yang of the yin and yang); with the unicorn and tiger; with the fur of an animal; with the direction of west; with the element metal; and with the Autumn season.[50]
In Japan, undyed linen white robes are worn by pilgrims for rituals of purification, and bathing in sacred rivers. In the mountains, pilgrims wear costumes of undyed jute to symbolize purity. A white kimono is often placed in the casket with the deceased for the journey to the other world, as white represents death sometimes.[51] Condolence gifts, or kooden, are tied with black and white ribbons and wrapped in white paper, protecting the contents from the impurities of the other world.[52]

Temples, churches and government buildings
Since ancient times, temples, churches, and many government buildings in many countries have traditionally been white, the color associated with religious and civic virtue. The Parthenon and other ancient temples of Greece, and the buildings of the Roman forum were mostly made of or clad in white marble, though it is now known that some of these ancient buildings were actually brightly painted.[54] The Roman tradition of using white stone for government buildings and churches was revived in the Renaissance and especially in the neoclassic style of the 18th and 19th centuries. White stone became the material of choice for government buildings in Washington D.C. and other American cities. European cathedrals were also usually built of white or light-colored stone, though many darkened over the centuries from smoke and soot.
The Renaissance architect and scholar Leon Battista Alberti wrote in 1452 that churches should be plastered white on the inside, since white was the only appropriate color for reflection and meditation.[55] After the Reformation, Calvinist churches in the Netherlands were whitewashed and sober inside, a tradition that was also followed in the Protestant churches of New England, such as Old North Church in Boston.

White is often associated with Monarchism. The association originally came from the white flag of the Bourbon dynasty of France. White became the banner of the Royalist rebellions against the French Revolution (see Revolt in the Vendée).
During the Civil War which followed the Russian Revolution of 1917, the White Army, a coalition of monarchists, nationalists and liberals, fought unsuccessfully against the Red Army of the Bolsheviks. A similar battle between reds and whites took place during the Civil War in Finland in the same period.
The Ku Klux Klan was a racist and anti-immigrant organization which flourished in the Southern United States after the American Civil War. They wore white robes and hoods, burned crosses and violently attacked and murdered black Americans.

Religion
In the Roman Catholic Church, white is associated with Jesus Christ, innocence and sacrifice. Since the Middle Ages, priests wear a white cassock in many of the most important ceremonies and religious services connected with events in the life of Christ. White is worn by priests at Christmas, during Easter, and during celebrations connected with the other events of the life of Christ, such as Corpus Christi Sunday, and Trinity Sunday. It is also worn at the services dedicated to the Virgin Mary, and to those Saints who were not matryred, as well as other special occasions, such as the ordination of priests and the installation of new bishops. Within the hierarchy of the church, the lighter the color, the higher the rank. Ordinary priests wear black; bishops wear violet, cardinals wear red, and outside a church, only the Pope will wear white.[57] Popes occasionally wore white in the Middle Ages, but usually wore red. Popes have worn white regularly since 1566, when Pope Pius V, a member of the Dominican Order, began the practice. White is the color of the Dominican Order.
In Islam, white clothing is worn during required pilgrimage to Mecca, or Ihram pilgrimage (Hajj).Hajj. Called Ihram clothing, men's garments often consist of two white un-hemmed sheets (usually towelling material). The top (the riḍā) is draped over the torso and the bottom (the izār) is secured by a belt; plus a pair of sandals. Women's clothing varies considerably and reflects regional as well as religious influences. Ihram is typically worn during Dhu al-Hijjah, the last month in the Islamic calendar.
In Judaism, during the rituals of Yom Kippur, the ceremony of atonement, the rabbi dresses in white, as do the members of the congregation, to restore the bonds between God and his followers.
In the traditional Japanese religion of Shinto, an area of white gravel or stones marks a sacred place, called a niwa. These places were dedicated to the kami, spirits which had descended from the heavens or had come across the sea. Later, temples of Zen Buddhism in Japan often featured a Zen garden, where white sand or gravel was carefully raked to resemble rivers or streams, designed as objects of meditation.[58]
In the temples of The Church of Jesus Christ of Latter-day Saints (LDS Church or also known as Mormon), White clothing is worn inside once they have been officially dedicated, due to white symbolizing purity.[59]
Many religions portray heaven as existing in the clouds, where everything is white. This phenomenon is not limited to western culture; in Yoruba religion, the orisha Obatala in the Ifá tradition is represented by white. Obatala is associated with calmness, morality, old age, and purity.
In Theosophy and similar religions, the deities called the Great White Brotherhood are said to have white auras.[60]
In some Asian and Slavic cultures, white is considered to be a color that represents death.[61] White also represented death in ancient Egypt, representing the lifeless desert that covered much of the country; black was held to be the color of life, representing the mud-covered fertile lands created by the flooding of the Nile and giving the country its name (Kemet, or "black land").

The white flag
A white flag has long been used to represent either surrender or a request for a truce. It is believed to have originated in the 15th century, during the Hundred Years' War between France and England, when multicolored flags, as well as firearms, came into common use by European armies. The white flag was officially recognized as a request to cease hostilities by the Geneva Convention of 1949.[63]
