Colour

Color is perceived by the human eye when light strikes a surface and is reflected. White light is partly reflected and partly absorbed. Depending on the amount of light reflected, we perceive a specific color. This process occurs in the brain after the eye (and its cones) are stimulated by visible light from a light source (see also color stimulus). The color stimulus, in turn, leads to color valence (perception), resulting in the experience and definition of color.
