High-LRV colors like Japanese Fern are forgiving in most lighting conditions, but they can pick up reflected color from adjacent walls, flooring, or large furniture pieces, so evaluate samples in situ. This tone works well alongside natural textures like jute rugs, bleached wood, ceramic tile, and woven baskets, building an inviting, tactile space. You can order Japanese Fern (400B-6) directly from Behr or through major paint retailers, and we recommend purchasing a peel-and-stick sample to preview it on your wall before buying gallons.
