The central problem in the philosophy of color is a special case of the problem of the manifest: How can colors as we perceive them be materially realized? To that extent, my research concerns a core problem in metaphysics. Specifically, I deny that colors are secondary qualities but are instead objective qualities of mind-independent particulars. In understanding how we can see colors so conceived, I make important claims about the nature of perceptual consciousness. To that extent, my research concerns the philosophy of perception and mind more generally. Specifically, I claim that perceptual color experience presents (rather than represents) the colors of remote external particulars. Since the view defended is an anti-modern view, this prompted me to revisit pre-modern views about color perception, and I have written a book on Empedocles and Aristotle on color perception.
