 Byrne and Hilbert (2011) provide a detailed examination of Color Dispositionalism, which they stress, can take different forms. They think that several of these forms can escape both the circularity and phenomenological problems, highlighted by McGinn, in part because they disagree with him on the phenomenology. They have different criticism of the theory: that there is no good reason for accepting the theory. They argue that the best reasons for accepting it depend on a highly implausible theory of perception.
