RAL 5013 Cobalt Blue

RAL 5013 Cobalt Blue (#1E213D) is a very deep, dark navy-blue from the RAL Classic system named after cobalt, the metallic element whose compounds have produced rich blue pigments since antiquity. This deep blue has aristocratic associations through Delftware, Meissen porcelain, and cobalt glass. It's used in premium ceramic specifications and prestige product design.

Dark blues like navy and midnight convey authority, intelligence, and unshakeable confidence. They are the color of police uniforms, corporate suits, and official documents worldwide. Navy blue inspires feelings of security and order, anchoring visual hierarchies with gravitas.

Dark blue is the premier choice for header backgrounds, navigation bars, and footer sections in corporate websites. It provides excellent contrast for white text and creates a sense of depth and professionalism. Pair it with bright accent colors like orange or lime for vibrant CTAs that pop against the authoritative background.
