I was thinking about color blindness (luckily an affliction that I do not suffer from). I realize that the people who do have this affliction do not see solely in black and white and do see SOME color...it's mostly a shading issue and that certain colors become muddied (green and red).
Because it's green and red, I'm curious about THIS:
While color blind people would still have normal everday regular life 3D depth perception, would they have artificial depth perception brought on by the 3D glasses since the lenses are one blue (sometimes green) and one red. Do they see a dual image? Do their eyes with limited color spectrum allow them to filter out the second image from each eye?
