In order to investigate the effects of visual stimuli from indoor plant, its picture, and various colors on the emotional response, visual preference, and brain activity, electroencephalography (EEG), thermal changes of the forehead skin using digital infrared thermal imaging (DITI), and emotional scale test were taken into healthy 25 college students selected as subjects. In the test of EEG with eye open state, newspaper stimulus as a control was compared with red, yellow, blue, and green color, Ficus benjamina and its photo with the same size, respectively. According to the results, green color, photo of Ficus benjamina, and real plants showed more increased activities in overall areas of the brain than other stimuli. Especially, real plant stimulus was more effective in improving brain activities than its photo. And also in the changes of the forehead skin temperature measured by DITI, blue or green-associated colors´ stimuli tended to descend the skin temperature more than red color stimuli with non-significant difference, however, indicating that the stimuli of former colors resulted in the sense of stabilization and shrinkage. Finally, green color-associated stimuli (green color, Ficus benjamina, and its photo) in emotional scale test showed more relaxed and happy feelings than other stimuli and, moreover, assumed to act as a stimulant improving judgement ability disorder often occurred in brain trauma patients.
