"With these three or six colours, which may be conveniently included in a circle, the elementary doctrine of colours is alone concerned."
Color is the visual perception produced by the activation of the different types of cone cells in the eye caused by light. Though color is not an inherent property of matter, color perception is related to an object's light absorption, emission, reflection and transmission. For most humans, visible wavelengths of light are the ones perceived in the visible light spectrum, with three types of cone
"[S]timuli above adaptation reflectance are tinged with the hue of the illuminant, stimuli below adaptation levels are tinged with the afterimage complementary to the hue of the illuminant, and stimuli at or near adaptation reflectance are either achromatic or weakly saturated color of uncertain hue."
Colors"Colour has a logic as exact as that of form. One must not give up before capturing that first impression."

Colors"Color is that aspect of the appearance of objects and lights which depends upon the spectral composition of the reaching the of the eye and upon its temporal and spatial distribution thereon."

I am always in hope of making a discovery there, to express the love of two lovers by a marriage of two complementary colors, their mingling and their opposition, the mysterious vibrations of kindred tones. To express the thought of a brow by the radiance of a light tone against a sombre background. To express hope by some star, the eagerness of a soul by a sunset radiance. Certainly there is nothing in that of stereoscopic realism, but is it not some thing that actually exists?"
