RAL 350 55 25

Bright Copper Penny

RAL 350 55 25 Bright Copper Penny is positioned at hue 350, lightness 55, and chroma 25, a vibrant mid-tone warm amber with the fresh appeal of a newly minted copper penny and the warm glow of polished carnelian gemstone. Designers specify it for creative branding elements, exhibition graphic panels, and contemporary furniture finishes. The balanced lightness and moderate-high chroma create a colour that is warm, invigorating, and unmistakably expressive.
