Seven Passions came from Chinese ethical and philosophical system by Confucius.
It focuses on human morality and right action. Also in Confucianism, they devided human feelings into Seven Passions : Joy, Anger, Sorrow, Fear, Love, Hate, Lust. I approached to each feeling with examining a color system.
