 The transparency argument can be extended also to the purely hallucinatory case. Suppose you are looking at a real, richly red tomato in good light. Suppose also that you then hallucinate a second, identical tomato to the right of the real one. (You may be aware that the second tomato is not real.) Phenomenally, the relevant two sectors of your visual field are just the same; the appearances are just the same in structure. The redness involved in the second-tomato appearance is exactly the same property as is involved in the first. But if we agree that the redness perceived in the real tomato is just the redness of the tomato itself, then the redness perceived in the hallucinated tomato—the red quality involved in the second-tomato appearance—is just the redness of the hallucinated tomato itself.
