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.

Nov 6, 2022 · The color matching test is the most significant test for tetrachromacy. It goes like this in the context of a research study: Researchers present study participants with a set of two mixtures of colors that will look the same to trichromats but different to tetrachromats.

Normal vision people have three types of neural signals going to their visual cortex - white/black, red/green and blue/yellow. The contrast between cyan and magenta is divine. The yellow glasses let cyan appear more green and the magenta glasses in contrast let cyan apear more blue.
