32 COLOR Colors may differ from one another also in apparent warmth, distance, weight, and acidity. These qualities in general have no firmer basis than our feelings about them. Warmth or Coolness. One of the most important qualities of color to be considered in interior decoration is its warmth or cool- ness. Colors that contain much yellow or red are considered to be warm; those that contain a preponderance of blue are regarded as cool. Green and purple are each made up of both a warm and a cool color. A yellowish green is likely to be warm; a blue-green is cool. A red-purple may be warm and a blue-purple cool. We probably attribute warmth or coolness to colors because of their associations with objects that have warmth or coolness. Yel- low and red seem warm to us because they are the colors of sun- shine, artificial light, and fire. Blue and green suggest coolness because we associate them with skies, water, ice, and foliage. In any color scheme either the warm or the cool colors should doimnate, equal amounts of each being unpleasant. All the warm colors are harmonious with one another because they belong to the yellow-red family, and the cool colors are friendly with one another because they are all related to the blues. Some decorators believe that the exposure of a room should in- fluence its color scheme; for example, a north room should employ yellow to produce a feeling of sunshine* Other factors such as seasonal use and climate also affect the selection of color schemes* Heaviness or Lightness. Studies are being made by psychol- ogists concerning the apparent weight or lightness of colors* Colorists agree generally that blue and purple are the lightest in weight of all colors. Green seems a little less heavy than red and yellow, which are the heaviest When the colors are grayed they tend to become alike in weight. In home decoration it should be* realized that heavy colors seem to belong to the lower part of a room, to the base. Reds, greens, and browns therefore tend to be desirable colors for carpeting. Heavy colors are good for a man's room or a library; lighter-weight colors are usually better in chil- dren's and women's rooms, depending, of course, on personal taste and coloring. Heavy colors are usually appropriate for heavy furniture, whereas light weight colors have a soaring quaEty that makes them more suitable for furniture of smaller scale,
