*Human skin color* is primarily due to *melanin<http://en.wikipedia.org/wiki/Melanin> *, it ranges from skin almost black in appearance to white with a pinkish tinge due to blood vessels <http://en.wikipedia.org/wiki/Blood_vessels> underneath.[1] <http://en.wikipedia.org/wiki/Human_skin_color#cite_note-0> Variations in skin color are mainly of genetic origin and are associated with sunlight but the evolutionary causes are not completely certain, the leading explanation is they are adaptations to sunlight intensities which produce vitamin D <http://en.wikipedia.org/wiki/Vitamin_D> deficiency or ultraviolet<http://en.wikipedia.org/wiki/Ultraviolet> light damage to folic acid <http://en.wikipedia.org/wiki/Folic_acid>.[2]<http://en.wikipedia.org/wiki/Human_skin_color#cite_note-1> Other hypotheses include protection from ambient temperature, infections, skin cancer <http://en.wikipedia.org/wiki/Skin_cancer> or frostbite<http://en.wikipedia.org/wiki/Frostbite>, an alteration in food, and sexual selection<http://en.wikipedia.org/wiki/Sexual_selection> .[<http://en.wikipedia.org/wiki/Human_skin_color#cite_note-Cite_pmid.7C19481954-2> 3<http://en.wikipedia.org/wiki/Human_skin_color#cite_note-Cite_pmid.7C19481954-2> ]<http://en.wikipedia.org/wiki/Human_skin_color#cite_note-Cite_pmid.7C19481954-2>
