Color vision is the ability of an organism or machine to distinguish objects based on the wavelengths (or frequencies) of the light they reflect, emit, or transmit. Colors can be measured and quantified in various ways; indeed, a human's perception of colors is a subjective process whereby the brain responds to the stimuli that are produced when incoming light reacts with the several types of cone photoreceptors in the eye.

Famous quotes containing the words color and/or vision:
“Gradually I regained my usual composure. I reread Pale Fire more carefully. I liked it better when expecting less. And what was that? What was that dim distant music, those vestiges of color in the air? Here and there I discovered in it and especially, especially in the invaluable variants, echoes and spangles of my mind, a long ripplewake of my glory.”
—Vladimir Nabokov (1899–1977)
“I’ve been cursed for delving into the mysteries of life. Perhaps death is sacred, and I’ve profaned it. Oh, what a wonderful vision it was. I dreamed of being the first to give to the world the secret that God is so jealous of, the formula for life. Think of the power, to create a man. And I did, I did it, I created a man. And who knows, in time I could have trained him to do my will. I could have bred a race, I might even have found the secret of eternal life.”
—William Hurlbut (1883–?)
