Three popular objections to reductionism about color, experience as of impossible colors, the unary/binary distinction, and structural mismatch, are issues just, I argue, for the (probably default) version of reductionism according to which colors reduce to sets of surface spectral reflectances (SSRs). They are not problems for the version on which colors are dispositions to reflect coarse-grained intensities of light—are what in colorimetry are called “object colors”. This paper sets out to demonstrate the virtues of the latter reductionism.
