Inorganic – A variant of Ultramarine pigment, a weaker, more violet pigment that has a relatively low Tint Power and a degree of transparency that lends itself to being exploited in glazes or thin body colour.
This colour is achieved by slightly altering the manufacture of the blue shade, Sodium Sulphosilicate, by heating it with Chlorine.
In hues, it becomes a high-keyed rather fluffy texture mauve which landscapists have found useful for the brighter tones of clear skies and for the modelling of sunlit clouds.
