Any visible color, as in the entire gamut of the human eye? =A0We'= ;re a long way off from that, I'm afraid. =A0Projectors are still makin= g images by shining red, green, and blue light up there, so that's a ma= jor constraint. =A0But you'd think they'd be able show everything w= e can see on a computer monitor at least. =A0Maybe they can.
