Rooms go quieter when soft blue is this sure of itself. The duck sits small and still, and the blue does the rest of the work. Put it up and a plain wall stops feeling like a gap the room reads calmer, cooler and a little more considered, without anything shouting. It suits a bedroom above the bed, a hallway at eye level, or a bathroom wall where the damp light flatters the loose brushwork. Pair it with linen, pale wood, cane and blue-and-white china. Keep the wall around it simple: heavy patterned wallpaper or a busy cluster of bold prints will fight the quiet and flatten the water. As a canvas, the paint-like surface reads closest to the original.
