Mali vs Senegal
Two copies of one picture score 0. Mali and Senegal score 37.3, and the app files them together as Pan-African Colors.
Where the difference is
Each colour on Mali, matched with the nearest colour on Senegal, and how far apart the two are — the number is the worst single tile, out of 255.
- #14b53a#00853f48
- #ce1126#e31b2321
- #fcd116#fdef4244
The colour that separates them is #14b53a against #00853f, 48 apart.
How they are put together
Both were measured as vertical bands.
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.
What it cannot see. Both are stretched to the same box, so the shape of the flag and how wide it is flown are gone — that is why Indonesia and Monaco, which differ in nothing else, are not measured as identical but as their reds. And a square is an eighth of the flag across, so a coat of arms, a star or a line of writing is averaged into the field behind it rather than counted as a difference.
