RAL 310 40 25

Vivid Fern Frond

RAL 310 40 25 Vivid Fern Frond occupies hue 310, lightness 40, and chroma 25, a bold high-chroma green-yellow that captures the electric intensity of unfurling fern fronds and the vivid glow of fresh watercress in spring sunlight. Designers choose it for eco-brand accent surfaces, creative studio feature walls, and bold architectural feature elements. The strong chroma at moderate-dark lightness delivers a colour that is both invigorating and strikingly alive in any built environment.
