They are usually pink, but sometimes change to a more brownish color. I thought the changes were just due to things like arousal, low temperatures, etc but it seems like there is no connection. It is almost like they just change at random. Why??? Also: before development i think they were always pink.. Created by Rosie. health-en - womenx27s-health-en

Nipples can change slightly in color for a multitude of reasons. Temperature, blood flow to the area, arousal, stimulation, time of day, position of the body... You're okay, it's completely normal. If they change to a very dark red or brown, call your doctor. c:
