What color is Dulux Winters Sky?

Dulux Winters Sky 81BG 12/055 is a deep, muted blue-grey with a distinctly cool, slate-like cast. Its low saturation keeps the color grounded rather than bright, making it a strong option for a study, hallway, or north-facing living room where lighter shades may feel washed out. In daylight, Winters Sky reads as a softened charcoal blue, while warm evening lighting can bring out its grey depth. Use it on full walls for a cocooning effect, or on cabinetry and interior doors against off-white walls. Pale oak, brushed nickel, black metal, and soft grey-beige textiles give this shade a clean, considered setting.
