What color is Dulux Buttercup Fool 1?

Dulux Buttercup Fool 1 45YY 64/787 is a clear, high-energy yellow with a warm golden cast. Its strong saturation gives it real presence, making it better suited to a feature wall, painted furniture, a front door, or kitchen cabinetry than to every wall in a small room. In bright daylight, this shade looks sunny and vivid, while lower evening light can draw out its richer, more honeyed side. Pair Buttercup Fool 1 with crisp white trim and pale timber for a fresh look, or ground it with charcoal, deep navy, or matte black accents. Natural oak, rattan, linen, and brushed brass all complement this color’s warm intensity.
