There’s a reason painters kept returning to hard-edged blocks of colour; rooms still respond. Put this up and a quiet room gets a proper focal point the mustard yellow warms cool daylight, and the pink and orange give the whole wall a lift you can feel from the doorway. It earns its keep above a sideboard, a desk, or on a short hallway wall where you pass it several times a day. Pair it with walnut or teak, chrome or brass legs, pale linen and plain stoneware so the colour does the talking. Don’t hang it beside busy patterned wallpaper or another loud abstract; give it clear wall on both sides. As a canvas the edges read softer and the colour feels more like paint on a wall.
