Various colors can be obtained by mixing three appropriately chosen chromatic lights. Such color matching experiments had been taken as strong evidence to support the trichromatic color vision theory. The function of color vision, the diversity of color vision research, and the mathematical expressions of trichromatic theory and its applications are explained in this article. Links between the fundamental principles of the trichromatic theory and various color applications are also stressed in the text.
