It might be a function of depth perception, like 3D glasses. My right eye seems to be color dominant. If I look at something and cover my left eye the color does not change. If I cover my right eye the color gets bluer.
You are astute to have nowiced that, Joe. I asked an opthalmoligist about it once, and he didn't know a thing about it. I first noticed it myself years ago when adjusting my binoculars.
How about a few others on the list checking it out and letting us know if it works that way with everyone, or are some of us different?

This brings up a question I have always wanted to ask -- related to the fact that my own two eyes see colors slightly differently! It's easiest to see in skin tones, but if I close one eye and then the other, it's obvious to me that my right eye sees a slightly "warmer" or redder rendition than my left. It's slight, and with both eyes open I suppose I see an average or mix of the two that isn't disconcerting, but it's obvious that at least slight differences must exist among people. Maybe wide ranges of difference are normal, like television sets where the tint is all out of whack and faces look green or magenta.
Has anyone tried this? It may be more noticeable in daylight or artificial light. Just a quick switch from one eye to the other and back should tell you.

I think its more likely that different eye/brain sets might see the same
colour very slightly shifted, one way or the other, on the spectrum. One
person might see it a little redder or bluer than another. But, as we
decided before, one can never really know. Its not the same as colour
blindness. My guess is that normal human eyes all see the spectrum the same
way and it is in the brain that differences might arise ... if they do.

I don't think it's empirically testable. If two people attach the same
label to the same experience then that is all we can know, or need to
know. I have no empirical evidence that other people think; you could
all be automata* as far as I know, but I assume that you all do think.
It's similar to the Turing** test, or these games of Chinese boxes that
AI researchers enjoy so much.

*as a matter of fact I happen to think exactly that, except that I include myself as an automaton. It doesn't alter the argument.
