Laos vs Vietnam
Two copies of one picture are 0% apart and the widest pair in the world is 100%.
Laos and Vietnam are 41% apart. They are closer than 95% of the flag pairs in the world.
Where the difference is
Each colour on Laos, matched with the nearest colour on Vietnam, and how far apart the two are, the number is the worst single tile, out of 255.
- #ce1126#da251d20
- #002868#ffff00255
- #ffffffonly on Laos
The colour that separates them is blue against yellow: #002868 against #ffff00, 255 apart.
How they are put together
Nothing about how they are built was measured the same on both.
Only Laos: horizontal bands, a disc. Only Vietnam: a single-coloured ground.
What each one carries
Laos carries a moon. Vietnam carries a star.
How the number was arrived at
Both flags are drawn at 64×48 and cut into squares 8 across. Each square is averaged to one colour, and the score is the worst single square, so two flags that agree everywhere except one corner are as far apart as that corner, which is the right answer to a question about whether anybody could tell them apart. 0 is the same picture; the number is the worst single tile, out of 255.
On that scale Laos and Vietnam score 105.5 out of 255, which is the 41% above.
It cannot see everything. Both flags are stretched to the same box, so Indonesia and Monaco, which differ in nothing else, are measured as their reds rather than as identical. The look-alikes page sets out the rest.
