The Korean flag is called Taegeukgi, where are a red and blue yin-yang symbol on a white field and four trigrams. The white background of the Taegeukgi symbolizes light and purity and reflects Koreans' traditional affinity for white. A taegeuk circle, divided equally and in perfect balance with red on top and blue below, represents the cosmic dual forces of yin (blue) and yang (red). It symbolizes universal harmony in which the positive and the negative or the active and the passive form a whole. The four trigrams that surround the taegeuk circle in the four corners denote the process of yin and yang going through a spiral of change and growth. The three unbroken bars in the upper left-hand corner denote geon ( heaven - justice), the three broken bars in the lower right-hand corner denote gon ( earth - fertility), the two broken bars with one unbroken bar in the middle in the upper right-hand corner denote gam ( water - life), and the two unbroken bars with a broken bar in the middle in the lower left-hand corner denote i ( fire - wisdom). Collectively the Taegeukgi represents universal harmony and unity.   Thus, the Taegeukgi embodies the ideals of Koreans who have pursued development and prosperity under universal principles and truth and circumscribes the country's tasks of unifying the people and working for world peace and prosperity.
