Melanin is the pigment that produces the shades and colors of human skin, hair, and eyes and the disorders in the production of melanin affects the color of your skin. Without melanin pigment, the skin would be white, or pale pink which is caused by blood flow through the skin. So, the fair skinned people produce very little, darker-skinned people produce moderate, and very dark-skinned people produce the most amount of melanin.
