  As explained in subsection 3.3, one may resist P3 by claiming that color experience represents appearance properties. That amounts to a defense of representationalism by introducing a distinction “at the level of reference”. However, P3 may also be denied by introducing a distinction “at the level of sense”. On this view, the difference between Invert and Nonvert is like the difference—as the Fregean has it—between Ian, who believes that Michael Caine is a Cockney, and Nan, who believes that Maurice Micklewhite is a Cockney. On this Fregean view of the content of perception, the difference between Invert’s and Nonvert’s experiences is that they represent the very same property, namely redness, in different ways, or under different modes of presentation.
