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:
“Good Hamlet, cast thy nighted color off.”
—William Shakespeare (15641616)
“Surely the day will come when color means nothing more than skin tone, when religion is seen uniquely as a way to speak ones soul; when birth places have the weight of a throw of the dice and all men are born free, when understanding breeds love and brotherhood.”
—Josephine Baker (19061975)
“The great God endows His children variously. To some he gives intellectand they move the earth. To some he allots heartand the beating pulse of humanity is theirs. But to some He gives only a soul, without intelligenceand these, who never grow up, but remain always His children, are Gods fools, kindly, elemental, simple, as if from His palette the Artist of all had taken one color instead of many.”
—Mary Roberts Rinehart (18761958)
