# Dulux Regal Purple

Source: [https://plan-home.com/color/regal-purple](https://plan-home.com/color/regal-purple)

Dulux Regal Purple 15RB 07/237 is a deep, muted purple with a noticeable blue cast, reading closer to inky violet than a bright jewel tone. Its low lightness gives it substantial visual weight, making it especially effective on a feature wall, built-in shelving, or lower cabinetry. In daylight, the blue undertone is likely to feel clearer, while evening lighting can draw out its darker, more shadowy character. Pair Regal Purple with soft greyed whites, pale stone, and natural oak to keep the room grounded, or introduce brushed brass for a warmer contrast. It suits bedrooms, libraries, and dining spaces where a darker wall color can create definition without appearing black.
