Michael Harding Paynes Grey - A blend of Ivory Black, Ultramarine and Iron Oxide Yellow, which gives a markedly cool black substitute. The blue undertones are similar to, but much milder, than those of Prussian Blue. Some painters prefer this blend for its restrained Tint Power, and use it in cool reflex tones in flesh painting
