According to the trichromatic theory, color vision is based on the response of three types of cones in the retina that produce different ratios of response to different wavelengths of light. These cones are sensitive to short (blue-violet), medium (green), and long (yellow-red) wavelengths of light, and the brain interprets the various ratios of stimulation produced by these cones as different colors.
