About RAL 590-1
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 590-1 from the RAL Effect — 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 590-1 on interior walls
RAL is defined for industrial coatings, not interior wall paint — so to paint a room in this colour you match it to a real interior brand. The Paint Matches above show the nearest RAL Effect 590-1 equivalent across 16 brands (Benjamin Moore, Sherwin-Williams, Behr, Dulux and more), each with its code, so you can take RAL 590-1 straight to a can.
