Detailed explanation-1: -Which of the following is a disadvantage of the trichromatic theory of color vision? It cannot adequately explain afterimages.
Detailed explanation-2: -In the trichromatic theory, there are three cones (RGB) in the retina that process long, medium, and short wavelengths to perceive color. There are three main colors: red, green, and blue (RGB). But trichromatic theory does not explain afterimages or color blindness.
Detailed explanation-3: -Trichromatic theory indicates that we can receive 3 types of colors (red, green, and blue) and that the cones vary the ratio of neural activity (Like a projection T.V.). The ratio of each color to the other then determines the exact color that we see.
Detailed explanation-4: -A basic problem with the trichromatic theory is that. four colors seem to be primary, that is, you cannot get them by mixing other colors.
