The possibility of a tetrachromacy mutation is only passed through the X chromosome. From our research so far, we know that the most likely candidates for tetrachromacy are those who carry the gene for very mild colour vision deficiency. oddly RGB on a computer produces a greater color spectrum than CMYK in print format, so these different colors would have to literally be mixed.

While your own chances of being a tetrachromat might be slim, these stories show how much this rarity continues to fascinate those of us who possess standard three-cone vision. Observing that signals from additional photoreceptors get used, and yield variation in perceptual experience, therefore requires an update to accepted theory.
