Inorganic – A deeper version of the Kings Blue Light blend. Useful for such features as architectural modelling in backgrounds, flowers, interiors, skies and accent colours.
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 I offer a completely reliable substitute blend that evokes the aerial effects of the great Venetian decorators.
