Flag of the Republic of Korea

The flag of South Korea, or Taegeukgi (also spelled Taegukgi in convention) has three parts: a white background; a red and blue taegeuk (also known as Taiji and Yinyang) in the center; and four black trigrams, one in each corner of the flag. These trigrams are carried over from the eight trigrams (Ba gua), which are of Daoist origin. Taiji, Trigrams and Taoism are parts of the Chinese Culture which influences Korea throughout history.

The white background symbolizes "cleanliness of the people". The Taegeuk represents the origin of all things in the universe; holding the two principles of yin and yang in perfect balance; the former being the negative aspect rendered in blue, and the latter as the positive aspect rendered in red. Together, they represent a continuous movement within infinity, the two merging as one.
