Almost a synthetic Cassel earth, cold, dark, bituminous...think a wet November evening about 5pm, when it should be light but it isn't. In masstone it is a bit like Burnt Umber but much cooler.
This has no red undertone, so it is excellent for cool shadows.
It also has some wonderful, rich grey tones when tinted with some white. So all in all a useful paint, and after all without dark there would be no light.
Pigment - Synthetic Iron Oxide, PBr6 / PBk11
Vehicle - Linseed Oil, Consistency - Butter
A nice paint - good smooth consistency - reminds me of Vasari paints. The colour is unusual in that used directly it bears some resemblance to a slightly cooler Burnt Umber but when white is added it tints more like Van Dyke Brown - but without the pinkish effect that many Van Dyke Brown's give. Cold Oxide Brown is a colour that has a unique twist to it - works well in flesh tones and in drapery I've found - I imagine it would be ideal for landscape and cityscape too.
