The statement that the nature of colorblindness depends on which of the three kinds of cones (green, red, and blue) is inoperative is true. Colorblind individuals may have trouble distinguishing between certain colors, but they are usually not completely unable to see any colors at all. Colorblindness is also much more common among men than women. Research on colorblindness actually supports the trichromatic theory of vision, which explains color vision in terms of three types of cones in the retina that are responsive to different wavelengths of light.
