When the living room feels over-arranged, this kind of botanical study helps. It gives the eye one clear place to land, and everything else can calm down around it. The blue flower head sits against striped coral orange, so the wall behind it reads warmer and the room feels less careful. Hang it above a sideboard, between two windows, or on a plain wall opposite the sofa where it can be seen from across the room. Keep the things near it simple: plain lamps, one plant, uncluttered shelves. Don’t crowd it with other strong-coloured pieces or hang it next to patterned wallpaper. It only works when it’s clearly the loudest thing on the wall. As a canvas the colour blocks read soft-edged and the frameless edge keeps it modern.
