What color is Dulux Chalky White 1?

Dulux Chalky White 1 10RR 73/023 is a pale, softly muted off-white with a faint rosy-grey cast. Its low saturation keeps the color looking restrained rather than pink, while the light value gives walls a gentle, powdery appearance. In daylight, Chalky White 1 reads as a clean warm-neutral white; under warmer evening lamps, its subtle blush undertone becomes more noticeable. It suits bedrooms, living rooms, and hallways where a stark white would feel too sharp. Pair it with weathered oak, pale stone, brushed nickel, charcoal accents, or deeper dusty rose tones for a considered layered scheme.
