Not because it’s navy, but because it refuses to fade back. Most rooms have one wall that never quite lands, and this is the piece that fixes it. The deep blue blocks give a pale room a proper anchor point, so the sofa, the rug and the lamp finally read as one arrangement rather than three separate choices. Hang it above a console, between two windows or on the long wall of a hallway where you pass it daily. Pair it with pale wood, off-white walls, linen and a bit of black metal. Don’t crowd it with small busy prints or heavy patterned wallpaper it works hardest with clear space around it. As canvas the deep blue reads matt and slightly softer across the wall.
