An article published on Medical News Today looks at research into skin pigmentation and how attractive we are perceived by others.
They cite a research paper from researchers at Bristol and St. Andrew Universities in the UK.

The melanin is thought to be involved in the immune system, but may contribute to vitamin D deficiency (presumably by making your skin darker, you need to spend longer in the sun to get your vitamin D). The carotenoids,
“signal health in bird and fish species, and are associated with improved immune defense, photoprotection and reproductive health in humans.”
