Solid Blacks. The solid black exercise previously described may be used in connection with pencil or pen effects by adding other details, either background or foreground, to the objects drawn in solid black. The best effects are secured by making these additions in a monotone, in order to secure a happy contrast between the two treatments. That is to say, no attempt need be made to blend the black subjects to the added detail.
