Human skin color is primarily due to the presence of melanin in the skin. Skin color ranges from almost black to white with a pinkish tinge due to blood vessels underneath. The term range is loosely defined in this case, as African albinos have obviously not been taken into consideration when calculating the range . The natural skin color can be darkened as a result of tanning due to exposure to sunlight. The leading explanation is that skin color adapts to sunlight intensities which produce vitamin D or ultraviolet light damage to folic acid . Other hypotheses include protection from ambient temperature, infections, skin cancer or frostbite , an alteration in food, and sexual selection . The social significance of differences in skin color has varied across cultures and over time, as demonstrated with regard to social status and racism .
