About RAL 5013
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 5013 from the RAL Classic — 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.
Matching RAL 5013 on interior walls
RAL is defined for industrial coatings, not interior wall paint — so to paint a room in this color you match it to a real interior brand. The Paint Matches above show the nearest Cobalt Blue equivalent across 16 brands (Benjamin Moore, Sherwin-Williams, Behr, Dulux and more), each with its code, so you can take RAL 5013 straight to a can.
