Since Dennett takes care to deny that there is anything that is actually colored, even in the mind, and that there are only words, dispositions to classify, and so forth, he arguably wishes to deny even that there is a "color feeling", though it's hard to be sure.

Citation or he didn't say it. Daniel Dennett coined the phrase "greedy reductionism" - partially to emphasize that he does not deny the existence of color, consciousness, etc. Unless you know of some place where he reversed his position, I would argue that you have misinterpreted his remarks. My understanding is that his position is that color is an idiosyncratic property of the human visual perception system with no simple referent in physics, not no referent at all.

(I normally wouldn't make such a big deal of it, but Dennett is one of the major figures on the physicalist side of this debate, and a mischaracterization of his views impedes the ability of bystanders to perform a fair comparison.)
