Tests for emotional harmony.—Important points to remember when making tests for emotional harmony are:

1. Low illumination with areas of shadow is restful, but high illumination is stimulating.

2. Horizontal lines and long, low shapes arouse a sense of repose, but vertical lines and tall narrow shapes have the opposite effect.

3. Dark colors (like low illumination and horizontal extension) affect the mind with a sense of repose, but pale colors (like brilliant light and vertical extension) affect it with a sense of animation and activity.

4. Large, heavy objects give a sense of repose, but anything small and light produces the opposite effect.

Bearing in mind these facts, turn on the ceiling lights in a room and notice the stimulating effect. Now turn off the ceiling lights and light the lamps in the room. Study the effect and you will see that the lamp-lighted room is more inviting.

In like manner, tests may be made to illustrate each of these points, such as substituting two high-back chairs in a room for the sofa. You will notice immediately that the room is less restful.
