Abstract
Red-, green-, and blue-colored paper stimuli were used to investigate the positive/negative emotions caused by
looking at these colors in relation to the simultaneously recorded brain activity. The left lateral activity on electroencephalography
(EEG), mental task performance, and the evaluation of color preference by the eight adult subjects
were used as indexes. The results showed greater left lateral activity in the alpha band during the closed-eye resting
period right after the subjects looked at red compared to the corresponding blue and green conditions. A significant
positive correlation was revealed between the color preference evaluations and the left lateral activities, and a significant
negative correlation was observed between the color preference evaluations and the activity at occipital regions
during the closed-eye resting period.
