There’s a reason illustrators keep returning to friendly dinosaurs; rooms still respond. A grinning triceratops in a flower crown gives a child’s room a focal point that feels gentle rather than loud. Put it up and the wall stops being blank filler: the warm clay pink and dusty terracotta pull heat into pale paint, while the dark green leaves stop the whole thing tipping into sugary. Hang it above a low cot, a changing unit, a small chest of drawers, or centred on a narrow wall between windows. Pair it with pale wood, rattan baskets, cream linen and a couple of terracotta pots. Don’t crowd it with bright primary-colour toy storage or busy patterned wallpaper; this one wants calm around it. As a canvas the surface is matt, so there’s no shine from the window.
