The North Korean flag is quite different from the South Korean flag although this did not avoid an embarrassing mistake during the first women's football match of the London Olympics between North Korea and Colombia.

The flag of North Korea consists of three horizontal stripes, two narrower blue stripes above and below and a larger red stripe in the middle. Inside this red, larger stripe there is a red star inside a white circle. Finally, the red stripe is delimited by two very thin white stripes.
