Hooker’s Green

Originally Gamboge mixed with Prussian Blue. Gamboge was impermanent, and as it faded the color would often take on a more dark blue color, but this dark green was popular and remains so, especially for watercolor. A dark green pigment was eventually given the name Hookers Green but it proved even less permanent than the original. Today the best colors with this name are mixtures of Pthalo Green and Burnt Umber or similar mixes.
