Quom live in the Astral Sea (which is sort-of like space) and can be various colours. Their description says they "have green, blue, or violet skin", but the illustrations include one that looks pretty pink to me.
Good old-fashioned Nordic humans will turn pink when exposed to several hours of strong sunlight. (Sunburn.) This also makes them very prickly and itchy, so they won't want anything / anybody touching them.
