What is the RAL colour chart?
It's actually a specialised system of multiple charts that define colours for paints, coatings, plastics, and other materials.
Developed in 1927 by the German Imperial Committee for Delivery and Quality Assurance, it features a total of 1687 shades across several charts. The RAL system allows you to reproduce a specific colour consistently across different surfaces and applications within Europe.
So you know that, when you pick your favourite colour for your aluminium doors and windows, that's what you'll get on the finished installed article!
While it's usually better to see these colours on a physical chart, for best representation, there is a website where you can explore the whole range!
