Before anyone mentions modern Matisse-style illustration, notice what the deep red does to plaster. The red vase pulls warmth into the room and gives chalky walls something to push against. Hang it where it can do real work above a sideboard in the living room, in a hallway with a console, or on a feature wall in a study. Pair it with cream linen, dark wood and a single terracotta pot. Brass picks up the warm reds. A pale pink or deep blue painted wall makes the whole thing sing. Avoid hanging it next to busy florals or other bold figurative pieces this one wants room to lead, not compete.
