Color theory has been worked on by a number of individuals over the years, and those with an interest in the field include artists, scientists, and of course, interior designers. Janet Ford, a web designer in Minneapolis, has been interested in this field for over a decade, and her website explores some of the issues surrounding color theory in a way that is both accessible and interesting. On the site, visitors can learn about the basics of color, complementary colors, and concepts such as contrast, dominance, proportion, and intensity. The site is rounded out by a very good “Resources” area, which contains a bibliography of recommended works drawn from the past several decades.
