Dulux Celestial Blue 4 90BG 21/302 is a clear, mid-depth blue with a noticeable blue-green cast, reflected in its crisp turquoise-leaning appearance. Its fairly strong saturation gives it enough presence for a feature wall, painted front door, or lower kitchen cabinetry without reading overly dark. In bright daylight, this color can appear cleaner and more blue-cyan, while lower or warmer light may draw out its deeper teal side. Pair Celestial Blue 4 with soft white trim, pale grey, light oak, or brushed nickel for a fresh, practical scheme. It also makes a confident contrast against warm terracotta, clay-toned textiles, and natural woven materials.
