What color is Dulux Open Sky?

Dulux Open Sky is a light, cool blue with a soft gray cast and a gentle hint of aqua. Its muted saturation keeps it from reading overly bright, giving walls a clean, airy appearance without becoming icy. In daylight, Open Sky can look clearer and slightly bluer, while warmer artificial light may bring forward its gray-green undertone. It suits bathrooms, bedrooms, and light-filled kitchens, especially alongside crisp white trim, pale oak, brushed nickel, and charcoal accents. Use this shade across full walls for an open feel, or on cabinetry and a single feature wall where a restrained wash of color is wanted.
