Once the lime green enters, the whole room stops apologising. A screen-print style landscape of blue hills and grasses cuts through beige rooms with confidence. Hang it above a console in the hallway, over a low sideboard in the living room, or across a study wall. It sits well with pale oak, cane, natural linen and plain painted walls. Skip it if the room is already loud with warm pinks, reds or heavy florals — those palettes fight the cool blues and acid green. Best framed simply in black or white so the colour does the work. Printed on premium fine-art paper for clean, saturated colour.
