About RAL 7021
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 7021 from the RAL Classic — 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 7021 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 Black Grey equivalent across 16 brands (Benjamin Moore, Sherwin-Williams, Behr, Dulux and more), each with its code, so you can take RAL 7021 straight to a can.

Our color tools run on our own catalogue of 26,000+ real paint colors across 16 brands — Benjamin Moore, Sherwin-Williams, Behr, Dulux, RAL and more — with the color math (HSL and CIELAB matching) computed in-house, not scraped from summaries. Every color you pick maps to a real, buyable paint with its code, so what you see here you can actually take to the store. We review and update these tools and their data regularly.
