Eye, hair and skin color vary around the world due to the production of a pigment called melanin. HERC2 is one of the genes responsible for melanin production and its effect can be seen directly from your eye color.

More about HERC2

Eye color is determined by how much light is absorbed when it enters the eye and is reflected by the iris. Melanin absorbs light; a greater amount of melanin makes eye color appear darker and vice versa.
