recently, it has been discovered that some people have an extra type of cone other than the three that most people with normal color vision have. what might be different for a person with a fourth type of cone?

Recently, it has been found that some individuals possess a fourth form of the cone in addition to the three that the majority of people with normal color vision do.

When a person has tetrachromacy, their retina has four cone types instead of the typical three that most people do. It is caused by a hereditary mutation and only affects women.

In the retina, cones are a particular kind of photoreceptor cell. They enable us to see in color. We can see fine details because of the macula, the area of our retina where cones are concentrated. The retina has about 6 million cones and 120 million rods. A photopigment in the fourth type of cone found in tetrachromats enables them to perceive more colors outside of the conventional visible spectrum. ROY G. BIV is a better-known name for the spectrum (Red, Orange, Yellow, Green, Blue, Indigo, and Violet).

Cone cells come in three different subtypes:

Red-sensing cones (60 percent)

Green-sensing cones (30 percent) and

Blue-sensing cones (10 percent)
