Same subject posted earlier in pencil . I love working with both mediums, so I did one of each. Why Not ? I don't own a tube of black. All my near blacks are made with either paynes gray or a blue ( ultramarine, indigo, plus Burnt Sienna) I'll sometimes add a touch of sap green, or if I want a reddish cast, alizaron crimson. Collar bones need softening . Yes!
