What color is Dulux Storm Day?

Dulux Storm Day 10GG 26/046 is a muted mid-tone green-grey with a gently softened, mineral-like character. Its subtle green cast keeps it from reading as plain grey, while the low saturation gives walls a calm, lived-in appearance rather than a strong hit of color. In brighter daylight, Storm Day can appear a little cleaner and cooler; under warm lamps, its grey base becomes more noticeable. It suits studies, hallways, kitchens, or exterior woodwork, especially alongside chalky whites, charcoal accents, pale oak, aged brass, and natural stone. Use it across full walls for a grounded backdrop, or on cabinetry where its restrained color can add definition without dominating the room.
