Why do people have brown eyes?
2
The brown color comes from melanin, the same pigment that colors the skin and makes a suntan. People with other colors of eyes generally lack melanin or have only small amounts.

Eye color is directly related to the amount of melanin in the front layers of the iris. People with brown eyes have a large amount of melanin in the iris, while people with blue eyes have much less of this pigment. A particular region on chromosome 15 plays a major role in eye color.
