There’s a reason Matisse kept returning to cut-paper shapes; rooms still respond. Put this up and a quiet, neutral room suddenly has a pulse. The bright red does most of the work, with deep blue and mustard yellow holding the corners so nothing tips over. It suits a plain cream or white wall where the colour has room to land: above a sofa, in a hallway, or on the wall you see first from the door. Keep the furniture calm around it, pale wood, linen, a plain rug, and let one accent cushion echo the red or blue. Don’t crowd it with other busy patterned pieces, and skip heavy dark walls, which mute the cream ground it needs. As a canvas the surface stays soft and glare-free in bright rooms.
