The Origin
In the last few years, there has been an increasing demand for a more comprehensive colour system than RAL CLASSIC, which, at 210 colours, is relatively limited, on the one hand, and lacks a systematic approach, on the other hand. So, the RAL DESIGN System with 1,688 systematically arranged colour tones was introduced in 1993.

The Colour Names
The colour name is composed of the three coordinates H, L, C.
-
The first value (hue) indicates the angle in the colour wheel (in the RAL DESIGN atlas, the value also indicates the page on which the colour can be found).
-
The second value indicates the brightness (lightness). In the atlas, this is the line in which the colour can be found.
-
The third value (chroma) determines the saturation. This determines the column in which the colour can be found.
The coordinate specification in the name of the colours allows any colour manufacture all over the world to reproduce a RAL DESIGN colour precisely – even without a colour sample.
