Michael Harding Artists Oil Colours - Aureolin (No. 501) - 40ml

Inorganic – Aureolin (Cobalt Yellow) is a transparent, straw, ochre-like yellow with rich, greenish undertones. It was produced in the 1850s as an inorganic replacement for the unreliable organic yellow gum known as Gamboge. In glazes and thinned layers, it displays a Renaissance-like range of muted gold, which over whites can be quite fiery. However, in or over deeper layers, Aureolin exhibits a mustardy, heavy patina. Mixed with PV 23, it can make a most remarkable deep, gingery colour.
