This illustrates the method of a neutralization toward the Middle Neutral, between Black and White, a neutralization in the measures of one quarter, one half, and three quarters.
In bringing tones into harmony, by one or another or all of these various methods, we must remember that when we have diminished the contrast of value and of color beyond a certain point the result is monotony, a monotony which may be undesirable. It is easy to get into a state of mind in which we dislike all contrasts. In this state of mind we find no æsthetic satisfaction except in monotony. Such a state of mind should be avoided. Monotony is the Nirvana of æstheticism.
168. We may have a Harmony in the repetition and recurrence of two or more contrasting, even strongly contrasting, tones. We may have Harmony in the repetition and recurrence of a contrast in which there is perhaps no Harmony.
For example: I may repeat the contrast Orange-Blue any number of times in a certain composition. There is no Harmony of Value or of Color in the contrast, but in repeating the contrast I have the Harmony of a Repetition, just as I have a Harmony in the repetition of a certain line or outline in which there is no order of any kind. The Harmony lies solely in the repetition or recurrence. In this way I may repeat, at equal intervals all over a certain space, the various contrasts indicated by the following diagram:—

There is no Harmony in the relation of tones here indicated, but we shall get Harmony in the repetition of this relation.
