Start with Forest Green on the walls. A powder room is small and gets used in short bursts, so it is the perfect place to be bold. This deep, slightly grayed green wraps the whole space and turns it into a quiet little jewel box. By candlelight or a warm bulb it reads almost black, rich and calm, and it hides fingerprints far better than a pale wall ever could.
Against all that green, Antique Gold does the showing off. It is a soft, aged gold, so it glows rather than glares, perfect for the faucet, the mirror frame, a light fixture, or a single framed print. Then Soft White keeps the room from feeling heavy: use it on the trim, the door, and the ceiling so the green has a crisp edge to stop against. Green on the walls, gold on the metal and the one thing you want noticed, and white framing it all.
