First read the paragraph below and then find out its problem in writing. Effects of Color Colors create biological reactions in our bodies. These reactions, in turn, can change our behavior. In one study, prisoners were put in a pink room, and they underwent a drastic and measurable decrease in muscle strength and hostility within 2.7 seconds. In another study, athletes needing short bursts of energy were exposed to red light. Their muscle strength increased by 13.5 percent, and the electrical activity in their arm muscle increased by 5.8 percent. Athletes needing more endurance for longer performance responded best when exposed to blue light. Blue is not a good color for dinnerware, however. Food look less appetizing when it is served on a blue plate, perhaps because very few foods are of that color. Other studies have shown that the color green is calming. After London’s Blackfriar Bridge was painted green, the number of suicides decreased by 34 percent. These and other studies clearly demonstrate that color affects not only our moods but also our behavior as well (Daniel 10)
