What color is Dulux Roman Stone 1?

Dulux Roman Stone 1 90YR 18/177 is a mid-depth earthy brown with warm, muted red and ochre undertones. Its softened saturation keeps it from reading overly orange, giving walls a grounded clay-and-weathered-wood character. In bright natural light, Roman Stone 1 can show more of its warm mineral cast, while evening light makes it appear deeper and more brown. Use it in dining rooms, studies, entryways, or on kitchen cabinetry where a substantial color is wanted without the heaviness of near-black brown. Pair this shade with chalky off-whites, sand-colored linens, aged brass, terracotta, and natural oak for a layered, material-led interior.
