Purple of Cassius. Purple of Cassius is a purple pigment formed by the reaction of gold salts with tin(II) chloride. ... The tin(II) chloride reduces the chloroauric acid from the dissolution of gold in aqua regia to a colloid of elemental gold supported on tin dioxide to give a purple precipitate or coloration.
