RAL 5004
Black Blue
RAL 5004 Black Blue is a near-black shade with a subtle blue undertone that reveals itself in bright, direct light. This deeply refined color offers architects and designers a sophisticated alternative to pure black, adding depth and complexity to metalwork, window frames, and facade cladding. Black Blue is particularly effective in contemporary minimalist design where its blue cast softens the starkness of dark surfaces while maintaining a commanding, authoritative presence.
