It is similar in a harmony of colors. For perhaps you see that what I wish you to understand is not that a few bright colors make a harmony, but that it is the result of a combination. There must be team-work among the colors. They count as individual spots of color, but still more in relation to all the other colors. There may be one or more crack players--I mean predominant[9] notes of color,--but they will have colleagues or assistants--colors of the same hue but differing in degree--which will repeat or echo their effect, with variations all over the canvas. These subordinate colors and the crack ones will play in and out, backing one another up, and, as it were, passing the ball backward and forward into one another’s hands; acting in such exact relation to one another, that their efforts result in a perfect harmony of effect.
