What color is Dulux Pebble Drift 1?
Dulux Pebble Drift 1 90BG 17/120 is a muted mid-depth blue-grey with a distinctly cool, lightly greened cast. Its softened saturation keeps it from reading as a bright blue, giving walls a grounded, slightly weathered appearance instead. In daylight, the blue-grey character is likely to feel clearer, while warmer artificial light can bring out its subdued grey tones. It suits studies, bathrooms, and north-facing rooms where a deeper cool color can add definition without becoming overly dramatic. Pair Pebble Drift 1 with chalky off-whites, pale stone finishes, brushed nickel, or light oak to create contrast and keep the scheme from feeling too dark.
