Skin color is determined by the number and type of melanin pigment. Pigment cells (melanocytes) of African-type skin produce a large amount of melanins that protect against excess UV radiation and give the skin a dark color. Melanocytes of the skin of the European type under the action of the UV radiation of the Sun in northern latitudes produce a much smaller amount of melanin. This skin has a light shade. In the skin of the Asian type, melanocytes also produce large amounts of melanin to protect against UV radiation from intense sunlight, due to which the skin has a yellow tint.
