A RAL code turns "dark grey" into a precise definition — a single defined shade that can be reproduced from batch to batch.
We work within the standard RAL range and source RAL, NCS or custom tones not on the list on request.
The code specifies colour, not surface: the same number comes in matte, semi-gloss and gloss, in smooth or textured versions, with gloss level agreed separately.
Screens and printed swatch books shift colour. For critical work we coat a sample panel first; the tone is approved under the actual light the part will live in.
