It is an evolutionary effect which has to do with geography and climate (where people have lived and what the amount of UV rays there is) and also with different diets. This article explains it quite well, in my opinion: http://humanorigins.si.edu/evidence/genetics/skin-color/modern-human-diversity-skin-color
On a related note, the fact that we are all very different is what makes us so interesting, isn’t it?
