Trichromatic theory

At the beginning of nineteenth Century, Yang (Young) and Herm Holtz (Helmholt Century Art), as figure 4.1 shown above the left, red, green and blue in proper proportion can be synthesized in a variety of colors, photoreceptors in the retina of eyes with figure 4.1 right above figure may be sensitive to red, green and blue three the color of the photoreceptor, accept the ratio of different color stimulus decided to see the colors, this is the Yang Yi Herm Holtz trichromatic theory.
