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.Tetrachromacy causes people to a. be more sensitive to blue light b. see perfectly in the dark c. distinguish more colours than the average person; Tetrachromacy has only been found in a. women b. young children c. artists; Scientists test for tetrachromacy by a. taking a DNA sample b. observing a person’s reactions to bright lightTetrachromacy is the rare ability to see up 100x more colors than the normal human eye can see.

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. Different groups of vertebrates have different numbers of cones, and therefore a different range and ability to discriminate colors. Birds, for example, are tetrachromats – they have four different cones and can see farther into the ultraviolet than humans. In fact the common ancestor of tetrapod vertebrates was likely a tetrachromat.

Unfortuantely there is no real solid test for tetrachromacy, so it has to be kind of a guessed diagnosis. Here's what my eye doctor emailed me when I asked him about it: Hi Alexis, While there isn't exactly a test that we could run to prove whether or not you have tetrachromacy, you still have the characteristics of a standard diagnosis.

Aug 1, 2016 · 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.

Claim: A rare visual condition known as 'tetrachromacy' cannot be identified with a simple online test. One of the easiest ways to test for tetrachromacy is by taking an online color vision test. There are several good options that present you with colorful dot tests and spectral bands to distinguish subtle shades and wavelengths that are indistinguishable to most people. Tetrachromacy is a visual condition that some women have in particular. It consists of having one more type of cone, which are the retina cells in charge of color vision.

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.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. However, the relationship between the existence of a fourth class of retinal cone and the dimensionality of color vision is more complex than previously thought.
