A single large five-pointed gold star, its points representing the five main classes - intellectuals, farmers, workers, entrepreneurs and soldiers - centers a plain red field, first used in 1940 and adopted by the Democratic Republic of Vietnam in 1945, with the current design set in 1955.

From this entry, not from the index: Shares its red-field, yellow-star communist iconography with China's flag, though Vietnam uses one large star rather than a five-star cluster.

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.
