What color is Dulux Sapphire Springs 2?

Dulux Sapphire Springs 2 50BB 11/321 is a medium-deep blue with a clear cool cast and a subtle green-blue edge. Its saturated depth gives it enough presence for a feature wall, while still feeling practical on cabinetry in a kitchen, utility room, or study. In bright daylight, this color reads as a cleaner, more energetic blue; under softer artificial light, it can appear darker and more subdued. Pair Sapphire Springs 2 with crisp off-white trim, pale grey, or light oak to keep the contrast fresh, or use warm brass and natural leather for added warmth. It is particularly effective on exterior doors, built-in shelving, and rooms where a stronger blue is wanted without moving into navy.
