Latvia vs Peru
The same colours, turned the other way. Latvia was measured as horizontal bands, Peru as vertical bands.
The tiles put them 68% apart, which is further than the 68% of a typical pair. A measurement answers whether two pictures match. People mix these two up because the colours do.
Where the difference is
Each colour on Latvia, matched with the nearest colour on Peru, and how far apart the two are, the number is the worst single tile, out of 255.
- #9d2235#d9102360
- #ffffff#ffffff0
The colour that separates them is a red: #9d2235 against #d91023, 60 apart.
How they are put together
Nothing about how they are built was measured the same on both.
Only Latvia: horizontal bands. Only Peru: vertical bands.
Latvia runs red, white and red from the top. Peru runs red, white and red from the pole.
Latvia is flown 2.00 : 1 and Peru 1.50 : 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 Latvia and Peru score 173.7 out of 255, which is the 68% 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.
