>I find tetrachromaticity fascinating -- particularly, I wish there were a way to scientifically prove whether tetrachromatics actually perceive colors as qualia that the rest of us don't, because that is absolutely not clear.

There is an African tribe that can see more greens and browns, due to their genetics and it has been proven for them.

Don't quote me on this, but I believe as a whole qualia has been proven. That is, we all do experience the world differently, but we can both point at the same thing and give it a same name. Words like 'red' are just pointers to the colors we see, and everyone sees it differently. This, ofc, doesn't guarentee we can see more or less levels of detail, just that we what we do see can be different.

I won't quote you... because qualia is not "proven". :) I mean, qualia exist obviously, but there is absolutely zero evidence one way or the other whether we perceive the same qualia or not. It's a completely open question in philosophy, because until we discover a way of analyzing conscious qualia using scientific instruments, there are no experiments we can imagine that would reveal a meaningful result.

It's not obvious qualia exist. For example http://cogprints.org/254/1/quinqual.htm
