Rublev Colours Pigment Mars Yellow - 4 oz

Mars colours are permanent pigments with good tinting strength in all mediums. Mars yellow, originally named jaune de Mars in the eighteenth century, is a high-tinting iron oxide pigment. The pigment’s very fine particle size gives it an intense colour.

Mars Yellow is one of the Mars pigments developed during the eighteenth century and manufactured by the aqueous precipitation of iron salts. Mars yellow is the first pigment produced by this process, which is then further roasted to produce the other Mars colours—orange, brown, red, and violet. Unlike other synthetic iron oxides and oxide hydroxides, the Mars colours were pure and fine-grained while retaining high tinting strength. Mars yellow is a yellow-brown shade. Mixing the iron sulfate raw material with alum could be brightened to a pale yellow before precipitating the iron oxide.

In his 1869 edition of George Field’s Chromatography, Salter gives Jaune de Mars, Jaune de Fer, and Iron yellow as synonyms for Mars yellow, adding that it was sometimes adulterated with orpiment or lead chromate to brighten the colour.
