Tetrachromacy, or the presence of a fourth cone class in the retina, results in exponentially enhanced color vision. While it is rare, it is even rarer to find functionality testing for it....
The spectrum of wavelengths we can see (visible light) ranges from 380 nm (blue) to 700 nm (red). Below this spectrum is ultraviolet, after which we have blue, and at the top of the spectrum of visible light is red, after which we have infrared.Scanning the eyes is not conclusive. In order to be tetrachromatic, you need to have not only four different “color” cones (different spectral responses), but they need to be connected to the nervous system to be processed in the brain separately. It is not that rare to have four sets of cones.Test yourself: is it additive colour or subtractive colour? ...

Aug 1, 2016 · “Unfortunately, computer screens do not provide enough colour information to be able to ‘tap into’ the extra dimension that tetrachromats may possess. It is therefore impossible for an online test to investigate tetrachromacy.” Even more absurd is that the online test I linked to claims that as many as 25% are tetrachromatic. The test found that about 50% of the general population get about 5 or 6 correct answers, while only 0.2% of people got all 10 correct. Another finding was that women seem to perceive color better ...The experiment tested the participants’ sensitivity to different levels of "luminance! at certain wavelengths of light; put simply, with Antico’s eye’s extra cone, she …I am not a tetrachromat but my wife is.

While it's difficult to test, enough tetrachromats have stepped forward that scientists now have visual and genetic tests for the condition. The subject hasn't been researched well enough yet for a reputable test to be created. It is theoretically possible to create such a test even with the standard video display devices which all have only three pixel colours, not four. Tetrachromats see the world a bit strange as their colour discrimination is higher due to some hue "remapping".
