Watch the stacked cubes land, then the magenta start doing damage. It reads as tidy geometry for about two seconds, then the bright pink and acid yellow take over the whole wall. A quiet room with plain walls and simple furniture suddenly has a focal point, and everything around it looks deliberate rather than beige. Hang it in a living room, a study or a home office where you sit and look at it properly, at eye level on a bare stretch of wall. Keep company simple: plain upholstery, pale or dark wood, black metal, one or two solid-colour cushions picked from the yellow or blue. Skip busy wallpaper, patterned rugs and other loud colour work nearby this one needs room to shout. On fine-art paper the flat colour blocks stay crisp and matt.
