The RAL D4 PLUS Colour Atlas is the standard library of the RAL DESIGN system and shows all 1,825 colours as original coating patterns displayed in a binder.
In the RAL DESIGN system the colours are arranged according to CIELab colour space by hue (H), lightness (L) and chroma (C) and the RAL D4 PLUS Colour Atlas displays the colours according to their position in colour space. Each page of the atlas shows a different hue with variations in lightness and chroma.
The measurement values of the colour features HLC lead to the seven digit number of RAL DESIGN colours, for example RAL 260 30 40.
