Before anyone mentions Pop Art, notice what the mustard yellow does to walnut. Warm timber suddenly looks richer, and an off-white wall stops reading as blank. The bloom is big and central, so it does the work of a much larger picture without adding clutter. Hang it above a sideboard, in a hallway that gets no daylight, or on the empty wall beside a kitchen doorway. Pair it with warm woods, tan leather, cane and plain textiles in mustard, clay or deep green. Keep the surrounding surfaces simple: no busy florals, no patterned wallpaper, nothing else fighting for the same red. As a canvas the colour sits softer and the edges wrap round the sides, so it reads more like a painted panel.
