The circular symbol in the center is called Taekuk, which is an ancient symbol of the universe showing opposition and balance. The upper section (yang) is red and the lower section (um) is blue.

The background is white and the bars in the corners are black.

The bars also symbolize the universe and reinforce the themes of balance and harmony of opposing forces. The bars in the upper left corner stand for heaven and the opposite bars for earth. The bars at the lower left stand for fire and the opposite bars for water.
