Nothing in this bold, sunny palette whispers, even when the living room does. Hang it where a room has gone a little too sensible and watch the mood lift. The pink buildings, blue sky and yellow cab bring colour without going chaotic, because the shapes stay clean and the drawing stays loose. It works above a sofa, in a hallway that needs a welcome, or in a kids' room where colour is the whole point. Pair it with painted timber, deep green plants, woven baskets and a striped cushion or two. Skip very serious, dark, formal interiors — this one wants a room that's already happy to play.
