Saunders & van Brakel set out to review color science
research and to topple the belief that color-vision neurophysiology
sets strong deterministic constraints on the cognitive processing of
color. Although their skeptism and mission are worthwhile, they fail
to give proper treatment to (1) findings that dramatically support
some positions they aim to tear down, (2) existing research that
anticipates criticisms presented in their target article, and (3) the
progress made in the area toward understanding the phenomenon.
At the very minimum these oversights weaken the credibility of their
arguments and leave the reader to wonder why their discussion ignores
what is clearly omitted.
