The RAL D2 fan deck shows all 1,825 colors of the RAL DESIGN plus system on 9 colors per page.
The finding of color shades is facilitated due to the arrangement of colors by the criteria hue (H), lightness (L) and chroma (C). The foundation of the RAL DESIGN system is the the CIELab color space, which is internationally used since 1976.
