The star inside the white disc on North Korea’s national flag is red.
The flag was adopted on September 8, 1948, when the Democratic People’s Republic of Korea was established. Its design places a five-pointed star inside a white disc near the hoist, against a broad red central stripe bordered by narrow white stripes and wider blue bands.
The star is commonly interpreted as a symbol of communism or socialism. The flag’s three main colors also carry political symbolism: red is associated with revolutionary traditions, white with purity and dignity, and blue with sovereignty, peace, and friendship. The white disc helps separate the star visually from the central red stripe.
A common mix-up is confusing North Korea’s flag with South Korea’s taegukgi. South Korea’s flag has a red-and-blue taegeuk and four black trigrams, while North Korea’s has a single red star. The flag was standardized in 1992, although its basic design dates to 1948.
