Ultramarine Violet (No. 208)

Inorganic

A variant of Ultramarine pigment. This colour is achieved by slightly altering the manufacture of the blue shade, Sodium Sulphosilicate, by heating it with Chlorine. The result is a weaker, more violet pigment which has a relatively low Tint Power and a degree of transparency that lends itself to being exploited in glazes or thin body colour. 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 modeling of sunlit clouds.
