PMJI The theory of trichromacy states that there are three kinds of color recieving cells (cones) in our retinas. The peak responsiveness of these cells hovers around the frequencies we would call red green and blue. The responsiveness of each kind of cell drops off as the frequency diverges from RG+B. Therefore the whole spectrum of frequencies you refer to are not only too much for our computers, but also too much for our eyes which essentially "sample" RGB frequencies at much higher rates than other frequencies. The efficiency of having only three color receptors that enable us to see more than 16.7 million colors is amazing. I agree that any color theory based on a pigment system is flawed. On top of that R Y B arnt even the right pigments as any printer knows. Sorry to butt in but I teach (and continue to learn ) color theory and I couldnt resist. Ed
