Michael Harding Kings Blue Light - This name was given by English manufacturers to Smalt, a Cobalt-based pigment that was used in the 16th -17th centuries as a less expensive alternative to Lapis Lazuli. Unfortunately, Smalt was prone to fade into a light grey, as some Veronese skies demonstrate. But the introduction of Ultramarine Blue made the original Smalt formula obsolete, and so Michael Harding offers a completely reliable substitute blend that evokes the aerial effects of the great Venetian decorators.
