No
No, most people have nipples that are darker(if only slightly) than the skin. This doesn't mean anything is wrong with you though. My friend's nipples are like that. Don't ask how I now :)
Nipple color is determined by genetics and the amount of melanin in the skin. There is no natural way to permanently change the color of your nipples. If you have concerns about the color of your nipples, it's best to consult with a healthcare provider for advice and guidance.
Your nipples won't darken.
There isn't one. its ok if you have brown or pink it doesnt really matter.
pink if she has red hair
fair hair
There supposed to be brown, I think.
i personally like brown nipples they are more appealing (they turn me on) but you have to be tan.
