Areolae which are notably dark in color, usually in shades of brown to black. Regarded in Japan as an accompanying sign of pregnancy or aging, while the more western pink-to-red spectrum is seen as a sign of youth.
Also applicable to any exotic skintone where the areolae are actually darker than the surrounding skin.
As with nipples/areolae, use this tag for images where only the the areolae is visible. For images where the nipple is fully visible, use dark nipples.
