Lemon Yellow is 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, Michael Harding is probably the only color maker to produce 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 color which does not discolor.
