131. One who attempts to make color compositions with no more reliable guide than taste can expect to accomplish no more than he who in music possesses a good ear but no musical training.
132. The note of discord in color is best avoided by an infallible guide, as the discord in music is best avoided by thorough training in the law of harmony. The color chart on page [73] has been so arranged that each of the shades is in exact harmony with the shade directly opposite.
133. For example, to ascertain the color that is in harmony with the shade denominated Red-Orange, it is necessary simply to lay a ruler across the diagram to find the corresponding harmony, which is Blue-Green.
134. We know that the primary colors are red, yellow and blue, and that the combination of any two of these gives a secondary color. The secondary color is the complement of the remaining third color; thus yellow and blue form green, and green is the complement or contrasting harmony of red. Red and yellow form orange, and orange is the complement of blue. Blue and red form violet, and violet is the complement of yellow. These are facts we all know. Now, if red is the complement or contrasting harmony of green, and yellow contrasts with violet, then red with one, two or three degrees of yellow added will contrast with green with one, two or three degrees of blue added.
