Rublev Colours Ultramarine Violetoffers a unique violet shade that is very clean, bright.

Ultramarine Violet is a synthetic inorganic pigment composed of a complex silicate of sodium and aluminum with sulfur, or sodium aluminum sulfosilicate. Ultramarine violet is made using the same process as ultramarine blue but is mixed with ammonium chloride, heated to 200–250° C., and exposed to air for four days until the violet color develops. Other methods are also used to produce ultramarine violet.

Permanence and Compatibility

Ultramarine violet is a synthetic violet pigment that is rated by the American Society of Testing and Materials (ASTM International) as lightfastness category I, which is the highest lightfastness. It is compatible with all pigments, resists alkalis, but has poor resistance to acids. Like ultramarine blue, it should not be used where acidic environments occur such as outdoors.
