About Cobalt Blue

Cobalt blue is a vivid, intense blue with a slight purple undertone. One of the most historically significant pigments, cobalt blue has been prized by artists and craftsmen since ancient times, used to color ceramics, stained glass, and paintings. It is one of the most saturated and visually striking blues, sitting between the calm of navy and the brightness of electric blue. Cobalt blue commands attention while retaining a sense of depth and sophistication.
