RAL 5013
Cobalt Blue
RAL 5013 Cobalt Blue is a deep, intense blue with a storied history rooted in the cobalt oxide pigments used in fine ceramics and porcelain since the Middle Ages. This rich shade carries associations with Delft pottery, Chinese blue-and-white porcelain, and traditional European tile work. In modern coatings, Cobalt Blue is specified for luxury interiors, museum installations, and architectural projects that reference historical craft traditions while maintaining a contemporary sensibility.
