Nipples 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 nipples are actually darker than the surrounding skin.
As with nipples and areolae, use this tag for images where the nipple is fully visible.
When the nipple is covered with the areolae peeping out, use dark areolae.
