It doesn't go by hair colour. It goes by skin colour.
If you're a pale-medium fair skin, they are more than likely pink/peachish. If you are below medium fair, then they will be tan-dark brown...
No
Some people have them, some people don't. You can;t make your nipples pink if they aren't naturally that colour.
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 :)
Your nipples won't darken.
