Color

Color

Color or colour (see spelling differences) is the visual perceptual property corresponding in humans to the categories called red, green, blue, and others. Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects, materials, light sources, etc., based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates.

Famous quotes containing the word color:

    “The most refined skills of color printing, the intricate techniques of wide-angle photography, provide us pictures of trivia bigger and more real than life. We forget that we see trivia and notice only that the reproduction is so good. Man fulfils his dream and by photographic magic produces a precise image of the Grand Canyon. The result is not that he adores nature or beauty the more. Instead he adores his camera—and himself.”
    —Daniel J. Boorstin (b. 1914)

    “Pockets: What color is a giraffe?
    Dallas: Well, mostly yellow.
    Pockets: And what’s the color of a New York taxi cab?
    Dallas: Mostly yellow.
    Pockets: I drove a cab in Brooklyn. I just pretend it’s rush hour in Flatbush and in I go.”
    —Leigh Brackett (1915–1978)

    “‘Twas mercy brought me from my Pagan land,
    Taught my benighted soul to understand
    That there’s a God, that there’s a Saviour too:
    Once I redemption neither sought nor knew.
    Some view our sable race with scornful eye,
    “Their color is a diabolic die.”
    Remember, Christians, Negroes, black as Cain,
    May be refin’d, and join th’ angelic train.”
    —Phillis Wheatley (c. 1753–1784)
