So if i show you a mixture of yellow and blue light, it will indeed look green. Then if show you monochromatic green light, it will look more green. Thus with any finite set of colors, you can't generate all the others, although you can get pretty close. The exception to this is purple, which, as pointed out before, is really only a mixture of red and violet. So if you mix together red and violet lights, you get something which is _really_ purple. --Joe
