Pigmentation, I guess. Some of us have very little. Mine are super-light pink!
Skin color, btw y were u wondering!?!?!?
Nipples are surrounded by an area of sensitive, pigmented skin known as the areola. The pigments of the nipple and areola are brown eumelanin (a brown pigment) and to a greater extent pheomelanin (a red pigment)--some people have more brown pigment than others. Pregnancy also increases the pigmentation of the nipples.
can you say why some people are black and some are white.....
tey get pinker the more they are sucked on.
