I don't even know how you can tell if one human perceives a color the same as
another human. How do you describe red without referring to something red?
Does it matter? However, if you cannot tell red from green, that is a problem,
no matter how you actually perceive it. Fish can distinguish one color from
another, however they perceive it.
