What color is Dulux Midwinter Tide?

Dulux Midwinter Tide 21BB 12/077 is a deep, muted blue-grey with a distinctly cool cast. Its low-saturation finish keeps the color grounded rather than bright, making it especially effective on cabinetry, interior doors, or a single enveloping wall. In daylight, Midwinter Tide reads as a restrained slate blue, while warmer artificial lighting can bring out its softer grey side. Pair it with chalky off-whites, pale stone, weathered oak, and brushed nickel for a clean, considered scheme. It also provides a strong contrast against light upholstery and natural linen textures without overpowering the room.
