We examined whether paper color affects the kind of emotional response obtained from questionnaires. University of Utah students (N = 221) read three vignettes, each describing a murder or rape, and responded by answering a set of eight questions for each case. A three-way analysis of variance was performed in which color (pink, blue, white), type of verdict (guilty, not guilty) and sex were the main effects. The results showed that there were significant differences for color and verdict but not for sex.
