Forest green is deep and slightly blue, the color of pine rather than leaves. In lingerie it is a winter color, common in velvet bralettes and bodysuits, heavy lace sets and satin robes in the months before the holidays, often sold as emerald, bottle green or pine.
Velvet suits it particularly well, since the pile shifts it from near-black to bright green as it moves. Dense dark-green lace can photograph almost black, especially on dark product backgrounds, so detail shots matter for this color.
Forest green pairs with gold hardware, burgundy, blush and ivory. The classifier separates it from green by depth and from teal by blueness. Under cool lighting, teal and forest green can be almost impossible to tell apart.
