Art Spectrum® Spectrum Blue is a vibrant and versatile blue formed from combing two classic pigments – Ultramarine and Phthalocyanine Blue. In effect it reproduces many of the characteristics of the great Cobalt Blue, but with the added economical and health advantages. Cobalt Blue was discovered in 1802 by the French chemist, Louis Jacques Thénard. However, we find earlier forms used for centuries in Chinese ceramics and European painting throughout the Middle Ages during which time it was made from coloured glass.
