Unfortunately this interesting pigment has been discontinued, however as of recently it was offered by four major paint brands, and may still be found in a few sap green blends.
It is like a much more vibrant earth tone, a sort of bright orange brown which thins beautifully. It's like a chromatic, rich, dark stained glass-like color, like a super-charged chromatic Burnt Sienna. It has excellent lightfastness in oil.
Along with Quinacridone Gold, PO49, it was smashing for botanicals and all kinds of realistic subjects.
