What is a RAL color?

RAL is the European color-matching standard used to specify exact colors for paints and coatings. Each code — like RAL 260 60 10 from the RAL Design System — maps to one defined color, 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.
