Overall, the results indicate that manipulating the color of the questionnaire had no effect on mood. However, there was an effect of time of day on mood as well as an effect of gender on mood. The results do not support the main hypothesis that different colors would elicit different moods. Thus, this study found no support for the prediction that brighter colors would elicit positive moods, whereas less bright colors would elicit negative moods. These results do not support previous research findings that brighter colors tend to elicit positive moods, whereas dark colors elicit negative moods (Hemphill, 1996; Kaya & Epps, 2004). Furthermore, this result was not expected given the previously discussed research by Weller and Livingston (1988) who found that manipulating color did indeed have an effect on an individual's mood. However, it is possible that the manipulation of crime vignettes used in Weller and Livingston's study was more powerful than our manipulation of asking people to rate their mood on the PANAS-X printed on different colors of paper . Another reason why the color hypothesis has not been supported could be because previous research has suggested that there are still mixed results on the mood elicited by each color as well as the hue , the exact saturation and brightness that a particular color must have to have a positive effect. effect (Valdez and Mehrabian, 1994). For example, research has suggested that one shade or tint of blue is not necessarily equal to another shade or tint of another blue (Eysenck, 1941). Thus, it should not be too surprising that the colors of the paper used in our study were not directly linked to a mood, given that we did not control the exact shade, tint, or brightness of the... .. middle of article......Journal of Social and Clinical Psychology, 25, 825-832. doi: 10.1521/jscp.2006.25.8.825Watson, D. and Clark, L.A.
