The RAL Effect collection gives the RAL Colour System greater variety in colour design. RAL Effect comprises 420 solid and 70 metallic colours. The 2 most important shade cards in the RAL Effect categories are the RAL E3 Color Chart & the RAL E4 Color Chart. It is the first colour collection to be based on waterborne paint systems, and no use is made of heavy metals such as lead, cadmium and chromates. RAL Effect allows eco-efficient colour production for all paints, lacquers and powder coatings thanks to its simple, modern formulation.
