AbstractColors seen together to produce a pleasing affective response are said to be in harmony. The term color harmony is not, however, a concise, descriptive term; rather, it is one with a wide range of meanings because of any or all of several conditional attributes. A content analysis was done on a selection of books from color science, art and design, color theory, and psychology. The study identified key attributes and related terms consistently used to describe color harmony. Categories of terms found to be coincidental with the discussion of color harmony were order, tone, configuration, interaction, similarity, association, attitude, and area. © 2002 John Wiley & Sons, Inc.
