Nope. Czechia has a blue triangle on its flag, which kind of « overlaps » with the red lower part. If it is removed, the overlapped part would become white too.
Excellent quiz! For Ukraine I kept at first thinking that yellow is the substituted colour for blue and I couldn't for the life of me think of a white-blue flag that would look like that :D
The vexophile in me started typing 'South Ossetia' just based on the tri-colours before I had to stop and try and lock back to what quiz I was taking ;(
Maybe it's my phone screen, but the one for Chile is orange. The rest are red,,,, and even the word "Chile" underneath the flag indicating I didn't get it are all definitely red. Chile's is definitely orange. Edit; it's definitely not my phone. Just googled "Chile flag", and it's definitely not the colour depicted in this quiz (i.e it's actually red, not orange)
That Panamanian flag is tricky without the blue!
Greece, Israel, Somalia, Finland, Honduras, Micronesia...
Great quiz
I love it
Nice idea!
