On a warm afternoon, the coral looks almost illegally fresh. That is the point of this one: it does the colour work so the rest of the room does not have to. A plain wall above a neutral sofa stops looking bare and starts looking deliberate, and the deep teal leaves quietly tie in any dark wood or petrol-blue upholstery you already own. Hang it above a sofa, a sideboard or a dining table where people sit long enough to pick out individual flowers. Pair it with cream linen, cane, warm brass and one or two pink or teal ceramics. Do not add a second busy pattern on the same wall, and skip competing brights in cushions and rugs. Let it lead. As a canvas the surface takes the glare off, which helps in a bright, sunny room.
