Emotion is the complex psychophysiological experience of an individual's state of mind as interacting with environmental influences. In this paper, we try to find the relation between colors, emotions and heart response using Triangular Phase Space Mapping (TPSM), a novel method for representation of heart rate. We used four colors as a visual stimulus while the lead II of ECG was recorded from 16 girls as subjects during the stimuli. The results show that colors blue, yellow, red and green induced emotions pleasure, sadness, anger and joy respectively. Kruskal-Wallis test was used to define the level of significance of each feature to demonstrate the usefulness of them in distinguishing responses to different colors and induced emotions. The results show that these features discriminate anger from sadness by p<;1E-3; anger from joy by p<;1E-5; anger from pleasure by p<;2E-4; sadness from joy by p<;2E-3; sadness from pleasure by p<;1E-2; and pleasure from joy by p<;1E-2.
