Jay Neitz is professor of ophthalmology and a color vision researcher at the University of Washington in Seattle, Washington in the United States. According to Jay Neitz, each of the three standard color-detecting cone cells in the retina - blue, green and red -- can pick up about 100 different gradations of color. But, he says, the brain can combine those variations exponentially, multiplying each new variety of cone by 100, so that the average human trichromat can distinguish about one million different hues (SOURCE: WIKIPEDIA).<br />
