Taegeukgi: Its design symbolizes the principles of the yin and yang in oriental philosophy. The circle in the center is divided into two equal parts, where the upper red responds to the active cosmic forces of the yang; conversely, the lower blue section represents the passive cosmic forces of the yin. The flag's background is white, representing Korean’s desire for peace and purity. The circle is surrounded by four trigrams, one in each corner, characterizing continual movement, balance and harmony. Each trigram symbolizes one of the four universal elements (heaven, earth, fire, and water).
