White is the combination of all the colors of the visible light spectrum.[1]. White is technically achromatic, and not a color, since it has no hue.
The impression of white light can be created by mixing appropriate intensities of the primary colors of light — red, green and blue — a process called additive mixing, but the illumination provided by this technique has significant differences from that produced by incandescence.
In nature, the color white results when transparent fibers, particles, or droplets are in a transparent matrix of a substantially different refractive index. Examples include classic "white" substances such as sugar, foam, pure sand or snow, cotton, clouds, milk, etc. Crystal boundaries and imperfections can also make otherwise transparent materials white, as in the case of milky quartz or the microcrystalline structure of a seashell. This is also true for artificial paints and pigments, where the color white results when finely divided transparent material of a high refractive index is suspended in a contrasting binder. Typically paints contain calcium carbonate and/or synthetic rutile with no other pigments if a white color is desired.
[edit] Etymology and definitions
The word white comes from the Common Germanic hwitaz though the Old English word hwīt.[2] The word designates the perception of light containing equal amounts of all wavelengths in the visible spectrum.

[edit] Paint
In painting, white can be crafted by reflecting ambient light from a white pigment, although the ambient light must be white light, or else the white pigment will appear the color of the light. White when mixed with black produces gray. To art students, the use of white can present particular problems, and there is at least one training course specializing in the use of white in art. In watercolor painting, white areas are the absence of paint on the paper. There are also speculations about the use of white and other colors.
[edit] White light
Until Newton's work became accepted, most scientists believed that white was the fundamental color of light; and that other colors were formed only by adding something to light. Newton demonstrated this was not true by passing white light through a prism, then through another prism. If the colors were added by the prism, the second prism should have added further colors to the single-colored beam. Since the single-colored beam remained a single color, Newton concluded that the prism merely separated the colors already present in the light. White light is the effect of combining the visible colors of light in equal proportions.
In the science of lighting, there is a continuum of colors of light that can be called "white". One set of colors that deserves this description is the color emitted via the process called incandescence, by a black body at various relatively-high temperatures. For example, the color of a black body at a temperature of 2848 kelvins matches that produced by domestic incandescent light bulbs. It is said that "the color temperature of such a light bulb is 2848 K". The white light used in theatre illumination has a color temperature of about 3200 K. Daylight has a nominal color temperature of 5400 K (called equal energy white), but can vary from a cool red up to a bluish 25,000 K. Not all black body radiation can be considered white light: the background radiation of the universe, to name an extreme example, is only a few kelvins and is quite invisible.
[edit] Standard whites
Standard whites are often defined with reference to the International Commission on Illumination's (CIE's) chromaticity diagram. These are the D series of standard illuminating. CIE standard illuminant D65, originally corresponding to a color temperature of 6,500 K, is taken to represent standard daylight.
[edit] Computer color temperature
Computer displays often have a color temperature control, allowing the user to select the color temperature (usually from a small set of fixed values) of the light emitted when the computer produces the electrical signal corresponding to "white". The RGB coordinates of white are (255, 255, 255).

[edit] Cultural symbolism
- White often represents purity or innocence in Western Civilization, particularly as white clothing or objects are easy to stain. In most Western countries white is the color worn by brides at weddings. Angels are typically depicted as clothed in white robes. In early film Westerns the stereotypically "good guy" wore a white hat (earning them the name "White Hats") while the "bad guy" wore black (earning them the name "Black Hats").
- This can be reversed as a deliberate play on conventions, by having the evil character dress in white, as a symbol of their hypocrisy or arrogance. For example, Don Fanucci in "The Godfather, Part II" is an evil character, but wears an expensive all-white suit as a sign of his power and prestige.
- In a highly-formal social function, the traditional dress for men attending is "white tie and tails"-- a white bow tie and a swallowtail coat.
- In ancient China, white was the symbol of West and Metal, one of the main five colors.
- In Indian tradition, white is also the color of death and ghosts, and also stands for Peace and Purity
[edit] Ethnography
- The term white is often used in the West to denote the race of fair-skinned Caucasoids people of European descent with pale to white skin color, whose skin color actually ranges from pink to pale brown. It has been suggested that the colors beige or peach are a more accurate representation of the color of most Caucasians. For more details, see Whites.
[edit] Geography
- Mauna Kea means white mountain in Hawaiian because, due to its high altitude, the top of this mountain is usually covered in snow during the winter.

[edit] Government and Industry
- A white paper can be an authoritative report on a major issue, as by a team of experts; a government report outlining policy; or a short treatise whose purpose is to educate industry customers. It is called white paper because it was originally bound in white.
[edit] Heraldry
- In English heraldry, white or silver (color) signified brightness, purity, virtue, and innocence. (The American Girls Handy Book, p. 369)
- Arthur Charles Fox-Davies has argued that white can be considered a tincture in heraldry separate from its use to represent argent, and in fact the labels borne on the arms, crests and supporters of members of the British Royal Family other than the reigning sovereign are invariably shown as white.
[edit] Literature
- White could be associated with horror. The famous chapter 42 ("The Whiteness of The Whale") of Herman Melville's Moby-Dick speculates about it.

(That is why they are called the Great White Brotherhood.) [4]
[edit] Politics
- The White House is the residence of the President of the United States.
- White is often associated with Capitalism (as opposed to Communism). This originated from Royalist rebellions against the French Revolution (see Revolt in the Vendée), known as the White terror.

In Japanese weddings, white is to symbolize the "death" of their former family and their introduction into their new family.

[edit] Sound engineering
- White noise, in acoustics, is a sibilant sound that is often a nuisance, although it can also be deliberately created for test purposes.
[edit] Sports
- White is the color of the usual cricket clothing, usually referred to as 'whites'. It is a result of cricket being a summer game with players being exposed to direct sunlight for prolonged periods of time.
- Australian Rules Football umpires' traditional uniform color is white. Nowadays most competitions (including AFL and VFL) provide other colors to ensure the umpires aren't clashing with players uniforms for higher visibility. At lower levels, however white is still the predominant color.
- White was originally the national auto racing color of Japan until international racing colors were abandoned due to sponsorship.
