Give the chalky dusty pink wall one hard decision, and let everything else relax. This is the piece that sets the tone, so the rest of the room can stay quiet. The mood shifts as soon as it goes up: dusty pink and dark green make a room feel like late evening, glass of wine already poured, music on low. Hang it in a dining room or a drinks corner, at eye level or just above a sideboard. Keep the surroundings simple warm timber, ribbed glass, a plum or green velvet chair, linen in oat. What it does not want is competition: skip busy pattern on the same wall, and give it room to breathe on its own. As a canvas the flat colour reads softly from across the room, with no glare from lamps or candles.
