Jan 1, 2016 · As 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. In the course of their search, Dr. Jordan's team has found many other people with four cones in their eyes, but none of them passed the test for "super colour vision."

The second was a multidimensional scaling test specially developed to reveal the extra dimension of color space expected to exist in the carriers of deuteranomaly.Dec 1, 2019 · Tetrachromacy, a phenotype arising from X-linked genotypic variants, is an exciting prospect and it now seems likely that there are individuals who fit the expected profile.
