With stacked cubes, scale decides whether the living room wakes up. Go big enough and this becomes the thing people look at; go too small and the pink and mustard blocks lose their punch. Hung above a sofa or a sideboard, it pulls colour out of cushions and rugs you already own and gives a plain wall a clear focal point. Keep the furniture around it simple teak or walnut, tan leather, plain upholstery, one or two stoneware pieces. Olive or off-white walls let the colour do the work. Don’t crowd it with other loud patterned pieces, and skip busy wallpaper on the same wall. Printed on premium fine-art paper, with clean edges that suit a sharp frame.
