Unlike most architectural art, this doesn’t wait for approval. Two blue shutters sit against a warm yellow wall with a slab of bright orange beside them, painted in thick, unfussy strokes. Hang it and a quiet room gets a proper focal point the sort of wall you look at instead of walk past. It works above a sofa, in a hallway where you see it head-on, or on a study wall facing a desk. Keep the furnishings plain: linen, cane, pale wood, a few stoneware pots. Skip busy patterned wallpaper and skip other loud colour nearby this piece only works when it’s the boldest thing in the room. On fine-art paper the ridges of paint stay sharp and the colour holds its edge.
