40 COLOR A Triad Color Scheme. This type of scheme combines the three equidistant colors, which occur at the points of an equilateral triangle placed anywhere on the color circle opposite. Turning the paper triangle will point out different combinations. A triad scheme is a well-balanced one, but the colors must be subdued to attain harmony. Some of the triads are: 1. Yellow, blue, red. 2. Yellow-green, blue-purple, red-orange. 3. Green, purple, orange. 4. Blue-green, red-purple, yellow-orange. A Complementary Color Scheme. Colors that are opposite on the color circle are used in this scheme. It is a stimulating type of color plan and is well balanced. The colors must be subdued, and one should dominate. A double complementary scheme in- volves two or more pairs of complementary colors. On the pig- ment twelve-color circle the complements are: 1. Yellow, purple. 4. Blue-green, red-orange. 2. Yellow-green, red-purple. 5. Blue, orange. 3. Green, red. 6. Blue-purple, yellow-orange. A Split Complementary Color Scheme, In a split comple- mentary color scheme one color is used with the two colors that adjoin its complement on a color circle. This plan produces some subtle combinations when the colors employed are properly sub- dued. Some examples of split complementary schemes are; 1. Yellow, blue-purple, red-purple, 2. Yellow-green, purple, red. 3. Green, red-purple, red-orange. 4. Blue-green, red, orange. Dominating Color, In any type of color scheme for any pur- pose one color should dominate in quantity, usually another color should be secondly in quantity, and if a third color is used it should be least in quantity. The smaller the area of a color the brighter it may be. See picture opposite page 46. Color Dissonances. In modern color study, as in music, atten- tion must be paid to dissonances as well as to harmonies. Such color schemes may be too difficult for students to create, but they are stimulating to see. The paintings of Henri Matisse of France sometimes contain color combinations that astonish the layman.
