Two uses of the analogy between colors and values

This paper distinguishes two different uses of the analogy between colors and values, the projectivist and the objectivist. The projectivist use of the analogy has a long history, which goes back to Hume. The objectivist use of the analogy is a fairly recent addition. The core contention of this paper is that the projectivist's use fails, and that only the objectivist offers a genuine use for the analogy between colors and values.
