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.Origins: On 28 February 2015, a fake online test for Tetrachromacy (a rare condition of having four cone cells in the eye) went viral on the social media site LinkedIn.

Normal colour vision depends on three types of specialised cells in the eye called cones. These cones are often referred to as blue, green and red cones depending on the particular wavelengths of light that trigger ... Since the tests aren’t calibrated for this wavelength, empirically demonstrating tetrachromacy is still really difficult. “Rainbow Gully, Mission Hills, SD” ConcettaAntico.comBut research into human tetrachromacy remains an emerging field with most discoveries still to come. Conclusion. Tetrachromacy is an intriguing and extremely rare variation in human color vision.

Since cDa29 could not make a trichromatic color match with only two primaries available in the Rayleigh region, she was classified as strong tetrachromat. Another approach to explicitly test for strong tetrachromacy is to ask candidates to discriminate surface colors. 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. This creates the effect of a "true-cyan" (google that), a more true mixture of blue and green. Compared to "true-cyan" normal cyan seems almost white. You would not flunk the Ishihara. Functional tetrachromats (1 in millions of people) see much wider ranges of colors than normal trichromats, and they pass Ishihara with ease.
