Open the curtains at mid-morning; the soft pink will handle the drama. It fills a small wall with warmth before anything else in the room has to try, and the blue-grey dinosaur gives a child something to greet, name and point at every day. Hang it low, above a cot, a toy chest or a little reading chair, so it sits at their height rather than yours. Pair it with pale wood, cream bedding, woven baskets and one or two other simple animal drawings. Don’t crowd it with busy patterned wallpaper or loud primary-colour posters, and don’t hang it high on a big empty wall where the small figure gets lost. On premium fine-art paper the flat colour stays clean and matt.
