A bedroom this pared back can take one serious blue. The room stays quiet, and this piece becomes the thing you look at first: two chalky shutters pushed open onto a hard, bright stretch of sea. It brings holiday light into a room without asking for a single other change. Hang it on the plainest wall you have, above a low chest of drawers or on a chimney breast, and let it run tall. Pair it with pale linen, whitewashed wood, cane and simple white ceramics. Do not crowd it with busy pattern or heavy dark furniture on the same wall, and avoid hanging it against a strongly patterned wallpaper. As canvas the thick brushwork reads clearly and the surface stays soft rather than glossy.
