White is the combination of all the colors of the visible light spectrum.[1]. It is sometimes described as an achromatic color, like black.

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.

Shade

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. There are also speculations about the use of white and other colors.

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.

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. Illuminated D65, originally corresponding to a color temperature of 6,500 K, is taken to represent standard daylight.

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.

White in human culture

Alcoholic Beverages

Animals

  • Butterflies of subfamily Pierinae of family Pieridae are commonly referred to as Whites, and the term forms part of many of the butterflies of this group, for example, Bath White.
  • Albino animals are considered sacred in almost all cultures.

Astronomy

Board Games

Computers

Cultural symbolism

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.

Futurism

  • White has also become a prominent color depicting technology and the future in the 21st century.

Geography

Gifts

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.

Heraldry

Literature

Magic (paranormal)

Meteorology

  • White is commonly the color of snow and ice.
  • Whiteout is a weather condition in which visibility is reduced and surface definition lost in snowy environments.

Military

Music

Parapsychology

Politics

Propaganda

  • Whitewash, figuratively, means an attempt to obscure the truth by issuing a blanket of lies. See propaganda. Also, it refers to the action of burying or shoving someone's face into the snow, as a form of bullying, or harassment(generally).

Psychedelic drugs

Religion

Romantic love

  • White is the traditional color of bridal dress in both western (European) and Japanese weddings. 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.

Sexuality

  • In the bandana code of the gay leather subculture, wearing a white bandana means one is into mutual masturbation.

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.

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.

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. [7]
  • 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."
