The loss of red, green, or violet as color perceptive elements in the retina causes an inability to perceive a primary color or any color of which it forms a part.A theory that seeks to elucidate the process of color vision in the human eye suggests that three distinct sets of retinal fibers are responsible for perceiving the colors red, green, and violet."}
