What the source says

Referenced, awaiting primary-source review
On 12 July 1948, the Constituent National Assembly adopted the taegukgi as the national flag. The color [white] represents peace and purity. The circle in the flag's center symbolizes harmony [...] the blue half represents negative energy (Yin), and the red half represents the positive energy (Yang). Together, the [four] trigrams represent movement and harmony as fundamental principles.

Most similar flags

The 6 closest of the 194 other national flags, ranked by a similarity index computed from the flag images themselves. The number is that index, 0–100 — not a claim that the two flags are “X% identical”.

Computed at build time: each flag is rasterised to 64x48, and the score is 0.55 × colour overlap + 0.45 × structure. A different weighting would rank these differently. How the index works.
