Deuteranomalous men with small Rayleigh matching ranges (good discrimination ability) are able to make discriminations not achievable by normal observers [19, 27, 28]. Calibrate your screen. Quick guide to get the best color accuracyAs expected, all control subjects failed to discriminate. 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.

You are wrong about tetrachromacy. Tetrachromats (type: yellow) can distinguish more colors in the same visible spectrum. Just like going from dichromacy to trichromacy your color vision is greatly enhanced, going from trichromacy to tetrachromacy results in an incredibly better color discriminability.

Observer compared a luminous circle 10ft away to test circles 10-120ft away On each trial the observer was to adjust the diameter of the comparison circle to match the apparent diameter of the test circleB) There exists no test to prove or disprove the existence of a functional tetrachromacy individual. C) The entire concept in humans relies on a theoretical behaviour of cone cell pigments that is yet to be empirically observed, despite being something that could affect anywhere from 15-50% of women and 8-15% of Men.That is not a test for tetrachromacy, although it is a decent way to identify color blindness.
