You don’t need more decor. You need one bird illustration with teeth. This one has a navy starling, mustard leaves and small hits of bright orange sitting on near-black ground. Put it up and a flat wall suddenly has a focal point the black holds its own against dark paint, and the orange does the work of an accent cushion. It earns its keep in a hallway, above a desk, or on a narrow bit of wall between doors. Keep the company simple: dark wood, black metal, one mustard or rust textile, matt ceramics. Don’t crowd it with busy patterned art or pale watercolours both will lose. On paper, the grainy texture and flat colour stay crisp.
