Melanin, a natural skin pigment, is responsible for giving your skin, eyeballs, and hair their characteristic color. Depending on the type and quantity of melanin present, these colors vary. When the melanocytes make less melanin, the hair and skin color are lighter, and if it is produced in excess, the color is darker. The body makes more melanin to protect your skin when exposed to sun rays.
