Sometimes known as Barium Yellow, as this is Barium Chromate. It was introduced into painting after the Lead Chromates, circa 1820. Unlike Lead Chromates, Barium has proved to be permanent and non-reactive. Often considered to be obsolete, I am probably the only colourman to make it. By itself an acidic looking yellow with weirdly green overtones, its low tint and covering power facilitates mixes with Magenta and the cooler reds, producing beautifully modulated greys sought in certain passages of flesh painting. The only yellow chrome colour which does not discolour.
