Overall, the results indicate that manipulating the color of the questionnaire had no effect on mood. However, an effect of time of day on mood was found as was an effect of gender on mood. The results did not support the main hypothesis that different colors would elicit different moods. Therefore, this study found no support for the prediction that brighter colors would elicit positive moods, whereas less bright colors would elicit negative moods. These findings 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 color manipulation had 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 colored paper. Another reason The color hypothesis was not supported may be because past research has suggested that there are still conflicting results about what mood is elicited by each color, as well as the exact hue, saturation and brightness that a particular color must have to have a color effect (Valdez & Mehrabian, 1994). For example, research has suggested that one shade or shade of blue is not necessarily the same as another shade or shade of another blue (Eysenck, 1941). Therefore, it should not be too surprising that the paper colors used in our study were not directly related to a mood, given that we did not control the exact hue, hue, or brightness of the…half of the document…. ..Journal of Social and Clinical Psychology, 25, 825-832. doi: 10.1521/jscp.2006.25.8.825 Watson, D., & Clark, L.
