England vs Guernsey
Two copies of one picture are 0% apart and the widest pair in the world is 100%.
England and Guernsey are 16% apart. They are closer than 99% of the flag pairs in the world.
Both are a red cross on white. Guernsey lays a yellow cross inside the red one; England leaves it plain.
Where the difference is
Each colour on England, matched with the nearest colour on Guernsey, and how far apart the two are, the number is the worst single tile, out of 255.
- #ffffff#ffffff0
- #c8102e#e8112d32
The colour that separates them is a red: #c8102e against #e8112d, 32 apart.
How they are put together
Nothing about how they are built was measured the same on both.
England is flown 1.67 : 1 and Guernsey 1.50 : 1.
What each one carries
Both carry a cross.
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 England and Guernsey score 40.9 out of 255, which is the 16% 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.
