34 COLOR THE EMOTIONAL EFFECT OF COLOR Our emotional reactions to certain colors are partly due to the symbolic meanings that have become associated with them. In the early Christian churches colors were used to convey definite ideas to the people who were unable to read. White was employed for innocence, black for evil or death, gray for penitence, red for love or martyrdom, blue for sincerity or hope, and the other colors for equally definite ideas. The color symbolism instituted by the church has been carried on by the theater up to the present time. Color, because of its emotional effect upon us, is largely re- sponsible for the atmosphere of a home. It is capable of soothing or irritating, cheering or depressing, charming or boring, welcom- ing or repelling. A color changes in emotional value if its hue, value, or intensity is changed. To illustrate: pure blue will have a different effect from greenish blue, which is unlike it in hue, or from baby blue, which is different from it in value, or from grayish blue, which does not agree with it in intensity. An important thing for a decorator to know is how to use color for its emotional effect. Different colors excite different emotional responses, and, too, some persons are more sensitive and more stimulated than others. Yellow, which is the color of the sun and artificial light, has an effect of cheerfulness, gaiety, buoyancy, optimism, exultation, sympathy, and even prosperity. It almost sings and shouts. For centuries it was considered a sacred color in China* In home decoration yellow is indispensable, because more than any other color it gives the effect of light. It supplies sunshine, even on a gray day. The modified yellows, such as buff, cream, ivory, beige, ecru, pale lime yellow, and pale banana yellow, are useful wall colors because they have the happy faculty of pulling together and harmonizing colors used in draperies, carpets, and upholstery. Yellow is a friend to the person with a limited income because it has the power of making inexpensive cottons, linens, and woolens look beautiful. Accessories of yellow are usually needed in north rooms* Gold, which is a type of yellow, is also useful; for example, a gold screen would add cheer to a dull room of the more elegant type. Yellow is also being used effectively fo* ex- terior house trimming, especially for shutters.
