Rublev Colours Ultramarine Violet offers 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.

Rublev Colours Cobalt Violet

The remarkable range of pigments that could be produced with cobalt included cobalt violet, is known since 1859. Salvetat first described the preparation of cobalt violet in Comptes Rendus des Seances de l'Academie des Sciences XLVIII in an article titled, "Matieres minerales colorantes vertes et violettes." The dark variety is anhydrous cobalt phosphate which was made by mixing soluble cobalt salt with disodium phosphate. It was washed and then heated at a high temperature.
