Depending on your genes, you can lose the amount of mellanin (skin pigmentation) over time due to a lack of Vitamin D which is what your body makes from the sunlight.

Why are there different colored skins?
Skin colors evolved mostly due to climates. In hot sunny places such as Africa dark skin is beneficial because melanin, the compound that makes skin brown, absorbs sunlight and prevents UV rays from damaging the skin, a sort of natural sunscreen. In colder, less sunny places such as northern Europe light skin is an advantage because you need to absorb as much sun as possible to get enough vitamin D from sunlight. Darker skin takes more sun to produce the same amount of Vitamin D as light skin.
Why do different races have different skin tones?
Skin color is determined by the amount/intensity of the sunlight affecting people where they lived over a long period. Dark skin is best in places where the sun is strong (the tropics) as it prevents the sunlight damaging the skin. Light skin is best in places where the sun is weak (the temperate regions) because sunlight needs to penetrate the skin to make vitamin "D" and dark skin prevents this penetration when the sun is weak. Therefore people with dark skin need to make sure that their diet contains extra vitamin D when living in temperate regions and light skinned people need to use sunscreen and cover up on tropical regions so that they do not burn.
