I dont have any knowledge on the subject but my opinion is that every
individual see a color in his own way. I mean you see the color "blue" as
"blue" but your neighbor could see it as "green". Of course it's blue for
him but it would be green for you. Nothing is harder to explain but maybe
you know what I mean. Your photoreceptors detect a specific wavelenght and
it's the same for everybody but how you "see" or "perceive" it in your
brain, I believe it's possibly unique to every individual. That would
explain why some people might hate a color when some other people might
enjoy it.

So no, you probably wont see the color "x" before you die but if you could
see what's going on in my brain when i detect colors, you could see it...

It's my first post here, I hope my comment make sense! It's kind of
fascinating the whole thing with the colors, colors don't really exist, it's
just the result of the light-object interraction.
