Exactly! But this apperition that "appears" to the perceiver, or his knowledge, whether altered or not, is still something. And what this is is a quale. True, ambient lighting and contiguous hues can alter our neural processes resulting in the various different particular apperitions that "appear" or the particular knowledge that results, but what appears, or the perceivers knowledge is what it is.

Yes, I can agree here. Qualia isn't just a set of physical blocks that our brain uses to build our conscious world of awareness. The way it is all unified (i.e. I know that red is very different than the smell of a rose...) is also important.
