Bahrain vs Qatar
Two copies of one picture are 0% apart and the widest pair in the world is 100%.
Bahrain and Qatar are 17% apart. They are closer than 99% of the flag pairs in the world.
Bahrain and Qatar are both white against red with a serrated join. Qatar is far the longer, and its red is the darker.
Where the difference is
Each colour on Bahrain, matched with the nearest colour on Qatar, and how far apart the two are, the number is the worst single tile, out of 255.
- #da291c#8a153880
- #ffffff#ffffff0
The colour that separates them is a red: #da291c against #8a1538, 80 apart.
How they are put together
Nothing about how they are built was measured the same on both.
Bahrain is flown 1.67 : 1 and Qatar 2.55 : 1.
What each one carries
Neither carries a charge. The difference is all colour and shape.
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 Bahrain and Qatar score 42.9 out of 255, which is the 17% 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.
