Some women are lucky enough to see colors beyond what the rest of us can imagine.

Tetrachromats have four color receptors rather than the regular three, allowing them to see colors the rest of us can’t even dream about. Because of genetic issues, it is impossible that a male could be a tetrochromat, and it is in fact more likely for males to be minus one of the regularcolor receptors, making them functionally colorblind.

A tetrochromat would have another color beyond the standard green, red, and blue trichromats experience, a color somewhere between red and blue, which would allow a tetrachromat to experience millions of extra colors when mixed with other shades.

However, even with an extra color receptor, tetrachromats still do not see colors above or below the regular range of human beings, rather, they see extra colors within the range.

Awesomeness.

in a chat we were just recently talking about certain people being able to see into the near ultraviolet parts of the spectrum. this is different, but still awesome.

question is, are these extra color receptors octagonal in shape, like in the discworld? because then we might have wizards ;)

    Unless something changed in the last few days, my understanding was that tetrachromacy has never been accurately...
