There is no call to treat illusory sensible qualities, and in particular colours, as actual qualities of actual entities. David Armstrong (1984) Many favor representationalism about color experience. To a first approximation, this view holds that experiencing is like believing. In particular, like believing, experiencing is a matter of representing the world to be a certain way. Once you view color experience along these lines, you face a big question: do our color experiences represent the world as it really is? For instance, suppose you see a tomato. Representationalists claim that having an experience with this sensory character is necessarily connected with representing a distinctive quality as pervading a round area out there in external space. Let us call it "sensible redness" to highlight the fact that the representation of this property is necessarily connected with the sensory character of the experience. Is this property, sensible redness, really co-instantiated with roundness out there in the space before you? 1 Since the development of the new mathematical physics of 17 th century, many prominent thinkers have returned a negative answer. Galileo, for instance, famously said that "tastes, odors, colors, and so on reside in consciousness", not the external world. Following this tradition, some contemporary representationalists hold that tomatoes and other objects are just collections of particles and fields lacking sensible properties. We evolved to have experiences that habitually misrepresent objects in space as having various sensible colors, only because this helps us to discriminate them from one another. However, other representationalists resist this radical irrealist view. They think representationalism about color experience goes best with "realism" about sensible colors. The tomato's surface really does exemplify sensible redness. In general, our color experiences typically represent objects as they really are. We will look at these different versions of representationalism. But first I will explain in more detail the basic representationalist approach they share.
