In restricting his analysis to the causal relations of functionalism, on the one hand, and the neurophysiological realizers of biology, on the other, Palmer has overlooked an alternative conception of the relationship between color experience and the brain – one that liberalizes the relation between mental phenomena and their physical implementation, without generating functionalism's counter-intuitive consequences. In this commentary we rely on Palmer's earlier work (especially from 1978) to tease out this alternative.
