Human skin color can range from almost black (in skin with very high concentrations of the dark brown pigment melanin) to nearly colorless (appearing pinkish white due to the blood vessels under the skin[. Skin color is determined primarily by the amount and type of melanin. Variations in skin color are mainly genetic in origin.
According to scientific studies natural human skin colour diversity is highest in black or sub saharan African populations.
In general, people with ancestors from tropical regions and higher altitudes (who were hence exposed to greater ultraviolet radiation) have darker skin than people with ancestors from middle latitudes. This is far from a hard and fast rule, however, because many light-skinned groups have managed to survive at the equator through social adaptation. The same can be said of dark-skinned groups living at subtropical and temperate latitudes.
