# Dulux Oxford Blue (Heritage)

Source: [https://plan-home.com/color/oxford-blue-uk](https://plan-home.com/color/oxford-blue-uk)

Dulux Oxford Blue (Heritage) is a deep, muted blue with a noticeable charcoal-grey cast that keeps it from reading as a bright navy. Its low saturation gives walls a grounded, slightly smoky appearance, especially in rooms with soft natural light. In brighter daylight, the blue becomes clearer, while evening lighting can draw out its darker graphite side. Oxford Blue (Heritage) suits studies, dining rooms, hallways, and built-in cabinetry where a substantial darker color is wanted without a stark black effect. Pair it with warm off-whites, pale stone, aged brass, natural oak, or cognac leather to bring warmth against its cool blue-grey base.
