Symbolism and history(r1)

A golden disc, offset toward the hoist to represent the full moon (which Palauans consider the optimum time for human activity such as fishing, harvest and celebration, and a symbol of peace, love and tranquility), sits on a plain sky-blue field, adopted at self-governance in 1981.

From this entry, not from the index: Its offset disc on a plain field echoes the structure, though not the color palette, of Japan's and Bangladesh's flags.

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.
