RAL 520-6 vs Black grey Color Comparison
Digital color is approximate.

Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. RAL 520-6 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
