What color is Dulux Earths Core?

Dulux Earths Core 30YR 18/596 is a deep, saturated red with a clear warm orange cast. Its strong pigment gives it real presence, making it especially effective on a feature wall, painted door, or kitchen island rather than across every surface in a small room. In bright daylight, Earths Core reads as a lively red-orange, while lower or warmer lighting brings out its darker, more earthy side. Pair it with chalky off-whites, warm beige plaster, charcoal, or natural oak to give the color breathing room. Matte black metal and woven natural fibres also provide useful contrast against this bold shade.
