What color is Dulux Silent Steel?

Dulux Silent Steel 30BB 45/015 is a light, low-saturation grey with a subtle cool blue cast. Its muted character keeps it from reading icy, while the gentle blue-grey undertone gives white-painted trim a cleaner, crisper contrast. In daylight, this color can appear softly silvery; under warmer evening lighting, it is likely to look more neutral and slightly deeper. Use it across living room or bedroom walls for a quiet backdrop, or on cabinetry where a pale grey alternative to white is wanted. Pair Silent Steel with chalky whites, charcoal details, pale oak, brushed nickel, and muted navy textiles.
