This paper reviews two studies of color preference and the relationships between color and legibility. The Gustin study in 1991 dealt with the legibility of and preference for projected slides with colored backgrounds and white text. The order of background color preference was cyan, blue, green, yellow, magenta, and red. The follow-up study by Cuttill in 1991 focused on the same variables viewed on a cathode ray tube. The order of background color preference was blue, cyan, magenta, red, green, and yellow. Based on the overall results of these studies, letter size and adequate contrast between lettering and background are the two most important criteria for producing materials with white lettering on colored backgrounds.
