some people like dark nipples, some people like pink nipples...i LOVE pale pink nipples. mine are sorta bright red right now, and when they're all puckered up, they're nearly black. it's freaky looking on my super-white chest.
but anyway, lost track of my point...some people develop an issue with their nipple color. after i got pregnant the first time, my fairly peachy nips turned dark red, and it's a bit embarassing for me. i don't like it. but i'll live.
mine are just slightly darker then the rest of my skin. They are kinda invisible. when aroused they are slightly darker...
it was worth a try.. but back to the subject.. mine are dark pink but turn a lot darker when i'm cold or just horny haha
