What is a RAL paint code?

A RAL paint code is the RAL colour reference number. The code only refers to the colour standard not the type of paint or other material.

Each standardised RAL colour is issued with a number or code. This number or code is used to define the standard colours for paints, varnish, powder coatings and plastics etc. RAL is the most commonly used Central European colour standard especially in architecture, construction, industry and road safety. The RAL Classic codes are four digits but the RAL Effect codes are 3 digits followed by a letter and the RAL Design codes are a sequence of three sets of numbers which refer to the lightness, chroma and hue of the colours.

Paint suppliers can match to a RAL paint code. They may request a colour standard if they are unfamiliar with the code supplied.
