 Before proceeding, there is an important point to clarify. Byrne and Hilbert, in their characterization of the problem of Color Realism, draw attention to the importance of our theories of perception in providing an account of colors. There is another aspect to their characterization, though the authors tend to downplay its importance. When Byrne and Hilbert introduce the problem, they take pains to emphasize that it does not concern, at least in the first instance, color language or color concepts.
