Tetrachromacy, just like Enchroma glasses, is fundamentally controversial. ~12% of women are carriers for R/G CVD, and they all have the first step to being a tetrachromat (having 4 cones), so its a good place to start, but having 4 cones is the easy part.

Tetrachromats can see colors that most people cannot — up to 100 million, estimates suggest, which is 100 times that of the average human. Most people have three cells, or receptors, in their retinas, but tetrachomats have a fourth receptor, which may be what allows for their heightened color perception.
