Once the mustard yellow enters, the whole room stops apologising. A hallway or living room wall that has sat blank for months suddenly has a job to do. Colour bounces off the wall and warms up the paint around it, so a plain cream room reads deliberate rather than unfinished. Hang it in a hallway at eye level, or above a low sideboard where the circular shapes can breathe. It sits happily with warm wood, cane, mustard or teal seating and simple cream ceramics. Keep the wall around it clear no busy patterned wallpaper, no competing bright posters either side. One strong piece does more here than three medium ones. On premium fine-art paper the flat colour blocks stay crisp and even.
