Undertone

About RAL 230 20 20
What is a RAL colour?
RAL is the European colour-matching standard used to specify exact colours for paints and coatings. Each code — like RAL 230 20 20 from the RAL Design System — maps to one defined colour, so a manufacturer or painter anywhere produces the identical result. It's used first and foremost on window frames, doors, façades, gates, railings and powder-coated metalwork.
Matching RAL 230 20 20 on interior walls
