The areola, surrounding the nipple, is often darker in a parous woman.
The region of black breast flesh that encircles the nipple is called the areola. Darker than the rest of the breast, the areola and nipple can range in colour from light pink in fair-skinned women to dark brown in others. The darker hue of the areola may serve as a visual cue to infants to close their mouths on the areola rather than just the nipple in order to get milk. The areola can be round or oval in shape and any shade of red, pink, or brown in hue. The areola may turn lighter once breastfeeding stops, but it often stays darker than it was before pregnancy.
