tetrachromacy is to discover (a) how the possession of extra photopigment opsin genes may alter perceptual processing of color, and (b) what the X-chromosome linked features of the L-cone, and possibly M-cone, opsin genes imply for potential human tetrachromacy and gender-linked color vision processing differences. From our research so far, we know that the most likely candidates for tetrachromacy are those who carry the gene for very mild colour vision deficiency.
