Not because it’s mustard yellow, but because it refuses to fade back. Three big flat flowers, stacked one above the other, give a wall a clear shape instead of a vague splash of colour. Put it on the narrow bit of wall a room usually ignores beside a doorway, above a low sideboard, at the turn of a hallway and that patch suddenly reads as deliberate. The deep plum holds its own against warm wood and leather, while the mustard picks up brass handles and rust textiles. Keep the surface below it simple: one lamp, one bowl, nothing competing. Avoid hanging it next to fussy florals or busy pattern the shapes here are big and want breathing room. On canvas the colour looks softer and more textural, with no glare.
