Less than 10 colors youre an assocrat. Most peoples colour vision is tri-chromatic, meaning their colour vision depends on three types of specialised cells in the eye, called cones. Tetrachromacy is the condition of possessing four independent channels for conveying color information, or possessing four different cones, one other than RGB.Organisms with tetrachromacy are called tetrachromats. Up to 12% of people with two X chromosomes may have the condition. Tetrachromacy exists in certain animals, like some birds, fish, insects, and amphibians. That mutation tacks on an extra type of cone to the usual three varieties humans are born with in their retinas, leading those with the condition to be able to experience a flood of rainbow hues.

According to the researchers at New Castle UniversitysTetrachromacy Project, standard RGB (i.e., red-green-blue) computer monitors are not capable of displaying the range of colors required to create a reliable online test for tetrachromacy: Unfortunately, computer screens do not provide enough colour information to be able to tap into the extra dimension that tetrachromats may possess. Tetrachromats are the name given to tetrachromic organisms. It is all quite interesting, but apparently is also highly obscure if all of those with a fourth cone cell do not have a functioning one.

For these organisms, the perceptual effect of any arbitrarily chosen light from its visible spectrum can be matched by a mixture of no less than four different pure spectral lights. 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). One percent of the worlds population is thought to be tetrachromatic. What is truly fascinating is that not everybody has just three variations of cone receptors, some have four and aretetrachromatic.
