RAL 7021
Black Grey
RAL 7021 Black Grey is a near-black grey that provides the depth of black with a subtle warmth that prevents surfaces from appearing stark or lifeless. This sophisticated shade is increasingly specified as an alternative to RAL 7016 by architects seeking an even darker, more dramatic finish for premium metalwork, luxury automotive components, and high-end interior features. Black Grey is particularly effective for large-scale facade applications where pure black might appear too harsh or absorb excessive solar heat.
