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:
“Painting seems to be to the eye what dancing is to the limbs. When that has educated the frame to self-possession, to nimbleness, to grace, the steps of the dancing-master are better forgotten; so painting teaches me the splendor of color and the expression of form, and as I see many pictures and higher genius in the art, I see the boundless opulence of the pencil, the indifferency in which the artist stands free to choose out of the possible forms.”
—Ralph Waldo Emerson (1803–1882)
“Good Hamlet, cast thy nighted color off.”
—William Shakespeare (1564–1616)
“For the profit of travel: in the first place, you get rid of a few prejudices.... The prejudiced against color finds several hundred millions of people of all shades of color, and all degrees of intellect, rank, and social worth, generals, judges, priests, and kings, and learns to give up his foolish prejudice.”
—Herman Melville (1819–1891)
