I know there is no scientific way to prove it one way or another, but could color be an innate quality of wavelengths? Could a perception of red or green or purple be universal if only slightly different due to slightly less efficient cone and rod configurations in some people? I know the acult might not be philosophical, but if one can confirm communication with those who have died, maybe the dead can see color without corporeal eyes? I ask because I have a retina disease now and my bad eye can often times see colors quite different from the good eye. It is nice to think that if someone ever had their eye regenerated in the future or a blind person seeing for the first time that there could be knowledge that you have in fact gifted them with what everyone else has.
