Dulux Regal Silk 36BB 15/398

Dulux Regal Silk 36BB 15/398 is a clear, medium-deep blue with a cool cyan cast that keeps it crisp rather than inky. Its strong saturation gives walls a defined presence, especially in a bathroom, home office, or modern kitchen. In bright daylight, Regal Silk reads as a lively blue; under lower or warmer lighting, it takes on a deeper, more shadowed character. Pair it with clean white trim, pale grey stone, light oak, or brushed nickel to emphasise its cool clarity. It is particularly effective on a feature wall, fitted cabinetry, or a front door where its concentrated blue can hold its own.
