By late afternoon, the hard-edged blocks stop looking decorative and start working. The bright pink and yellow shapes catch the last of the side-light and lift a flat, quiet wall without needing a single other thing on it. Hang it where the room already has a plain surface to give: above a low sideboard, on a chimney breast, or on the wall behind a desk. Keep the furniture calm and let the colour do the talking. Tan leather, teak, black metal and plain linen all sit happily under it. What not to do: don’t crowd it with patterned wallpaper, busy shelf clutter or a second bright abstract nearby. Printed on premium fine-art paper, so the flat colour stays clean and matte.
