An Iron Oxide manufactured to such small pigment particle size that it shows, like its Yellow counterpart, almost lake-like characteristics. Terrific tint power which produces wonderful results in mixes with yellows, and which can give gravity to mid-red tones.
It also makes fantastic rich, warm blacks and dark tones when mixed with greens, it can hold its own against something like a permanent green. It is a very functional and useful colour.
Personally I find it extremely useful when mixed with Ultramarine blue for creating warm/cool greys depending on the balance of the colours.
