the combination of three or more related colors or hues, showing a gradual change from one color to another, with a dividing line or border separating the colors from one another; for example, take any third section of the chromatic circle on Plate 32.
The Harmony of a Dominant Color is produced by a combination of colors, in which one of them predominates to such an extent that it gives the whole design or figure the appearance of being delicately tinted with that color. This harmony is best illustrated by viewing a pleasing combination of colors through a delicately tinted glass. It is also frequently seen in spectacular plays, when a colored light is thrown upon a scene which is composed of a harmonious arrangement of colored objects. An imperfect illustration of this harmony can be had by viewing Plates 49 and 67 through the tinted sheets which precede them.
By Harmonies of Unrelated or Contrary Colors, is meant the harmony of two or more colors which are not related to each other—-and which are, therefore, located some distance from each other in the chromatic circle. For example, red is not related to yellow or bine, or any color lying between them; yellow is not related to red or blue, or any color lying between them; and blue is not related to red or yellow, or any color lying between them.
The Harmony of Distant Colors — Equal, in Tone, is produced by the combination of two colors which are complementary, or nearly so—each being about equal in depth of tone; for example, see Figs. 245, 251, 264, 274, and many others in this work.
The Harmony of Distant Colors—by Contrast of Tone , is produced by the combination of two colors which are complementary, or nearly so, and between which there is a decided difference in tone; for example, see Figs. 256, 257, 258, 262, 263, 266, 269, and others in this work. Fig. 313, Plate 46, is a fine example of the harmony of distant colors—by contrast of tone; it shows a combination of six colors and gold.
