From Light to Color: the Path of Seeing the World
Human vision is the resultant thing when the organism encounters light, the abundant physical stimulus in our world. However, vision is not the world. Human vision just represents the physical world in the brain reasonable for the organism, but not for the real world, as observed in the phenomena of visual illusions. Human vision, especially color perception in the present review article, can be thus understood from disciplines of physical sciences, psychophysics, physiology, and psychology, as different processes on the path of seeing the world. The physics of light is itself the origins of color studies, which is about the spectrum, radiometry and photometry, colorimetry, and metamerism. Among those physical phenomena of color, color mixtures are operated with physical stimuli, but seen with psychological principles, where color psychophysics was founded on. Color vision also plays an important adaptive role for organisms. Animals with color vision can easily identify ripe- fruits, tell who its mates are, and find enemies. In a modern human society, colors are used as codes for almost everything that needs to be separated and visually discriminated. However, we have to make it clear about what is color before we study color. Color is a pure visual phenomena, which does not exist in the physical world but only a product of vision, and color vision deficiencies are not rare. The application of color involves technology and aesthetics. Accurate measurements of color are essential before creative color design can be used on mass production. In the end, we point out that color is not merely like a red, green, yellow, or blue. All visual senses about surface, e.g., glossiness, transparency, hardness, wetness, etc., should be considered as colors in the visual world.
