RAL Colours

Problems that you can simply brush over. You probably know the RAL colour numbers in the form of 4-digit code under the RAL Classic system.

A tip: If you work with RAL numbers, please also state the colour name so that RAL 1023 ("traffic yellow") is not accidentally mixed up with RAL 1032 ("broon yellow"). Here, you can find a list of all of the RAL colours - from "telemagenta" to "pearl copper".

With 210 colours, the choice is rather limited. In order to offer a greater variety, another system - RAL Design - with 7-digit codes (and 1688 colours) was created. Details concerning the "RAL - Deutsches Institut für Gütesicherung und Kennzeichnung e.V." (German Institute for Quality Assurance and Vertification) can be found under

Pantone® Matching System (PMS)

In the graphics and printing industry, the PMS ssytem that was developed in the US in 1963 is the most common colour system. The strength of the Pantone system is the fact that it provides special colous that cannot be reproduced by way of four-colour-printing.
