About mustard
Mustard is a deep golden yellow — a saturated, warm colour that reads as mid-toned. As a warm tone it looks most resolved next to cool and neutral partners that temper its warmth, and it needs both lighter and deeper shades nearby for the value contrast the eye reads as finished. That balance is what makes it feel serene in walls.
