RAL colour chart
Please note that our ColourTEK system can reproduce any colour for our products, not only the trade colours displayed above.
Due to various reasons, an accurate virtual representation of a RAL colour is not always possible. Physical colour swatches have painted representations of colours, and these can be found at any TeamFrames branch.
