Cones are responsible for your ability to see colors. It results from a genetic mutation. 6% of men carry an anomalous gene which produces a different red or a different green cone. We say humans are trichromats because we have cells in our eyes that can pick up three broad wavelength bands: red, greenand blue. Tetrachromatics have four cone types in the back of their eyes (normally people have three).

But in some rare cases, it can also be an acquired trait. 2-3% of women, however, retain the four cones of tetrachromacy. Insects exhibit some of the more impressive systems: bees are tetrachromats (4-colour) and can see more ultraviolet light than humans, and many butterflies are pentachromats (5-colour).

Tetrachromats have one extra type of cone that allows them to see a fourth dimensionality of colors. But all of his tests showed that these women could only perceive the same colours as the rest of us - which meant only three of their cone cell types were working, so they weren't true tetrachromats. This molecule is known as 11-cis retinal. In tetrachromatic organisms, the sensory color space is four-dimensional, meaning that matching the sensory effect of arbitrarily chosen spectra of light within their visible spectrum requires mixtures of at least four primary colors.

For the chemical ion species, see Tetrachromate. The normal explanation of tetrachromacy is that the organism's retina contains four types of higher-intensity light receptors (called cone cells in vertebrates as opposed to rod cells, which are lower-intensity light receptors) with different spectral sensitivity.
