A response to Sydney Shoemaker's "Content, Character, and Color". Whereas "Metamerism, Constancy, and Knowing Which" argues that different qualitative aspects of a color are perceptually available to a perceiver in different circumstances of perception, the present paper argues that different qualitative aspects of a color are perceptually available to different perceivers in the same circumstance of perception. Understanding how this could be so undermines Shoemaker's criticisms.Article
