EFFECTS OF 3 COLORS IN AN OFFICE INTERIOR ON MOOD AND PERFORMANCE

This study examined the effects of three hues on subjects' performance and mood while in an office work environment for 1 hour. Pretest/posttest measurements were completed. Work performance was measured using words typed, typing errors, and a ratio of errors to words typed. Anxiety, depression, and arousal were measured by the Eight State Questionnaire of Curran and Cattell. A total of 45 women, ages 18 to 24 years, were tested individually in a single office space: 15 when the office walls were painted red/warm, 15 when walls were blue-green/cool, and 15 when walls were white/neutral. Analysis of covariance of posttest measurements with the pretest as a covariate showed no significant differences among the three groups on performance or scores on anxiety, depression, and arousal. If color of the environment has an effect on work performance or mood, either the effect was too small to be detected with samples of 15 subjects or longer participation than one hour was required.
