What’s the living room missing? Deep red with some nerve. This one walks in and takes the wall, so the rest of the room can stay simple. Neutral sofas suddenly look deliberate rather than safe, and a plain painted wall stops feeling like a gap. Hang it above a sideboard, over a low console, or on the wall you see first from the doorway. Pair it with warm timber, aged leather, chunky wool and a couple of teal or mustard cushions picked straight out of the fringe. Keep the wall around it clear and skip busy patterned wallpaper alongside it, or the two will fight for attention. As a canvas, the painted edges and texture read straight off the wall.
