Skin color is determined by pigment (melanin) made by specialized cells in the skin called melanocytes. The amount and type of melanin determines a person's skin color.
Melanin gives color to the skin, hair, and the iris of the eyes. Levels of melanin depend on race and amount of sunlight exposure. Sun exposure increases melanin production in order to protect the skin against harmful ultraviolet rays. In addition, hormonal changes can affect melanin production.
