Where the sun is strongest, skin colour has become darkest, while weak solar radiation gives light skin colour.

Dark-skinned people need six times more sun than white-skinned people to get enough Vitamin D. On the other hand, they have less chance of developing skin cancer.

Most probably the skin tone varies depending on the amount of sun's radiation. Although it does not completely depend on the sun's radiation. It also varies depending on the gene and the food style.
