Researchers from the University of Essex in England designed a study to investigate how color affects the mood of those mid-workout. In it, 14 college-age men rode stationary bikes for three five-minute periods while watching a video clip of nature scenes. Each video had a color filter that rendered the image green, then black and white, then red for one of the three five-minute periods. Between each segment, the subjects answered questions about their mood. The researchers found that subjects reported more energy and better mood following the green-hued nature scenes than after black and white and red ones. What’s more, the red-hued screens made participants feel angry.
