White is a color, the perception which is evoked by light that stimulates all three types of color sensitive cone cells in the human eye in near equal amount and with high brightness compared to the surroundings.
Since the impression of white is obtained by three summations of light intensity across the visible spectrum, the number of combinations of light wavelengths that produce the sensation of white is practically infinite.

White is a color, the perception which is evoked by light that stimulates all three types of color sensitive cone cells in the human eye in near equal amount and with high brightness compared to the surroundings.
Since the impression of white is obtained by three summations of light intensity across the visible spectrum, the number of combinations of light wavelengths that produce the sensation of white is practically infinite. There are a number of different white light sources such as the midday Sun, incandescent lamps, fluorescent lamps and white LEDs. The impression of white light can also be created by mixing appropriate intensities of the primary colors of light — red, green and blue (RGB) — a process called additive mixing, as seen in many display technologies.
White light reflected off objects can be seen when no part of the light spectrum is reflected significantly more than others and the reflecting material has a degree of diffusion. This is seen 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, and milk. Crystal boundaries and imperfections can also make otherwise transparent materials white, as in the milky quartz or the microcrystalline structure of a seashell. This is also true for artificial paints and pigments, where 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.
Etymology
The word white comes from the Common Germanic hwitaz though the Old English word hwit.
Shade
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 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.
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. When mixing paints in order to get a lighter color, it's advisable to mix a small amount of color to white, rather than trying to add white to the color, as it will take considerably more paint to get the desired tint.
Objects
While the color of a light source can be reasonably measured by its correlated color temperature, a different approach is required for objects since different samples may appear white without a reference. Thus, assessment of whiteness requires a comparison. The International Commission on Illumination (CIE) prescribes one such method.
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).
In human culture
Asian culture
- In China, traditionally, white was the symbol of West and Metal, one of the main five colors.
- In Indian tradition, white is also the color of purity and sacredness. It is also used for depicting Peace and Purity. However it is also the color of mourning. People wear white after death of any of their family members.

beige or peach
Ethnography
- The term white is often used in the West to denote the race of pale-skinned Caucasoids people of European descent with pale to white skin color, whose skin color actually varies widely from pale 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.
Geography

- 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.
Heraldry
Horticulture
- Senecio cineraria is an old fashioned and popular garden plant due to its white-wooly foliage.
Literature
- White could be associated with horror. The famous chapter 42 () of Herman Melville's Moby-Dick speculates about it.

Military
- A white flag is an international sign of either surrender, or truce, that is, it is a sign of peaceful intent, typically at time of war.
- To "show the white feather" is to display cowardice. In cockfighting, a white feather in the tail is considered a mark of inferior breeding. In Victorian England a purported coward would be presented with a white feather.

In Western weddings, a white dress is thought to be symbolic of purity (the bride has not engaged in pre-marital sex). This is also said to be the symbolism of the veil. In Japanese weddings, white is to symbolize the "death" of their former family and their introduction into their new family.
Sexuality
- In the bandana code of the gay leather subculture, wearing a white bandana means one is into mutual masturbation.

- In baseball and basketball, white is the color typically used for uniforms worn by the home team.
Symbolic dualism with black
- 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 esteem, power and prestige.
Television
- In Western TV programs, and Western movies, the "good guy" usually wears a white hat. But in the dramatic series Dallas, J. R. Ewing wears a white hat in defiance of this convention, inasmuch as there is nothing "good" about him.
Vexillology
- Vatican City has a flag of yellow and white (although in normal European heraldry one is not supposed to use these two colors together because both represent metals--yellow represents gold and white represents silver), to show that the Church is not bound by secular rules.
- In the Ethnic Almanac, under the heading of the Irish, it says that on the flag of Ireland the green stands for the Catholics, the orange for the Protestants, and the white for the unity between them. The Almanac says about this, "No comment."
