The next step is to mix three values, light, medium and dark, in three
white dishes. The intervals can be tested by painting the spaces of a
simple scale. This need not have an outline, as three brush‐strokes will
suffice. Apply these tones to a design; make several arrangements, for the
effect, and to discover the possibilities in three values. The subjects
might be the same as in notan of two values, pages 63—68. The examples
below illustrate the method and results. See scale, p. 88, also p. 9. In
addition to original composition, the student should copy from
masterpieces of design and pictorial art, translating them into three
values.
