First of all, it is important to understand how eye colors are determined. Eye colors are determined by a pigment called melanin that is produced in a layer of tissue behind the iris, which is the colored part of the eye. If a person has a lot of melanin in their iris, they will have dark brown eyes. If they have very little melanin in their iris, they will have gray or light blue eyes. And if a person has an average amount of melanin in their eye, then the color of their eyes will be determined by how much and what type of melanin is present.
Melanocytes are cells that produce pigment and distribute it to other cells. These melanocytes are found throughout the body, but they’re most concentrated in skin and hair. In the iris, two types of melanin exist: pheomelanin, which is red-brown in color; and eumelanin, which is black or dark brown. The type of pigment present will determine the color of your eye.
If a person has a lot of pheomelanin, but very little eumelanin in their iris, then their eyes will be red-brown or hazel in color. If they have lots and lots of both kinds of melanin, then their eyes will appear to be dark brown or black. The quantity of melanin present will affect the size and shape of your iris, as well.
For example, the more melanin you have in your iris, the larger it will be. Will’s eyes are hazel because he has a mix of both kinds of melanin in his eyes.
Melanin is most concentrated in our skin and hair because it protects us from harmful ultraviolet rays (UV rays) from the sun. So, people with a lot more melanin in their hair and skin will have darker hair, eyes and lighter skin. People who have less melanin will have paler skin and lighter hair and eyes. There are some eye colors that are not due to this either including green, blue or hazel which is really just several different colors mixed together.
