What color is Dulux Plum Custard?

Dulux Plum Custard 15RB 28/271 is a muted mid-tone blue-violet with a softly greyed cast. Its cool lavender character is clear without becoming overly bright, giving walls a gentle wash of colour rather than a sharp purple statement. In daylight, Plum Custard can read slightly bluer and quieter, while warmer evening lighting tends to draw out its violet side. It suits bedrooms, reading rooms, and calm living spaces, especially paired with warm white trim, pale oak, brushed nickel, or charcoal accents. Use this shade across full walls for a cocooning effect, or on cabinetry and interior doors where its subdued depth can stand out against lighter surroundings.
