RAL 280 55 20
Warm Buttercup
RAL 280 55 20 Warm Buttercup sits at hue 280, lightness 55, and chroma 20, a warm earthy mid-tone yellow with the comforting softness of buttercup petals and the muted warmth of sun-kissed meadow grass. It brings approachable warmth to garden centre display elements, organic brand packaging surfaces, and residential living room feature walls. The moderate chroma at mid-high lightness creates a colour that is atmospheric yet easy to coordinate with neutral palettes.
