 There is an added complication. Of those philosophers who assume that visual experiences have representational content, some, like Jackson, do so within a framework in which the content is conceptual, while others such as Tye, Byrne, and Hilbert, take it to be non-conceptual. Furthermore, there are yet others, such as Peacocke 1984/1997,  who hold that there are two distinct aspects to color experiences, one non-conceptual, the other conceptual. Peacocke defends a theory in which “looks red” is confined to the conceptual, representing sense. On this account, we must distinguish between two aspects to the visual experience had, when S sees a red object, and where it looks red to her; (1) a sensational property red* is presented to S, in a region of her visual field; (2) S is in (or has) a state which represents, conceptually, to S that X (or at least something) is red.
