TONE-HARMONY
162. By Tone-Harmony I mean a relation of likeness in tones. Tones are in Harmony when they resemble one another in all or in certain respects. To be in Harmony two or more tones must have at least something in common, either value or color. If they have the same color they may be in the same degree of intensity, giving a Harmony of Intensities. Tone-Harmony resolves itself into Value-Harmony, Color-Harmony, and the Harmony of Intensities. The Harmony of Intensities lies between tones of the same color, when they are equally neutralized or neutralized in approximately the same degree. When different colors are neutralized we have the Harmony of a common neutrality or grayness of color.
163. Tones may be harmonized on the palette before they are used, that is to say, before any positions, measures, and shapes are given to them on paper or canvas, or they may be harmonized after positions, measures, and shapes have been given to them. To harmonize tones on the palette, as to value, we must bring them approximately to the same value, with as little change of color as possible. To harmonize tones on the palette as to color we must bring them approximately to the same color, with as little change of value as possible. If two or more tones have the same color they may be intensified or neutralized until they are brought approximately to the same degree of intensity. The tones of Red showing a Harmony of Intensities would lie on a vertical line drawn through the triangle of Red in the [Diagram of the Triangles].
As the tone-effect which we produce depends very largely upon the positions, measures, and shapes which we give to our tones, we may not be satisfied with an effect which has been produced with previously prepared and harmonized tones. We may wish to change the effect, to achieve a still greater Harmony. Given a certain arrangement or composition of tones, certain tones in certain positions, measures, and shapes, and given the problem to harmonize those tones, what do we do?
164. Suppose it is Value-Harmony which we want; what is our procedure?

Here, let us say, are the tones of a design, certain colors in certain values. What shall we do with these tones to bring them into Value-Harmony?
