There are too many countries in the world, and even though it'd be interesting to cover all of them, there are a few sets of flags \[0] that look _very_ similar. Namely:

* Chad and Romania
* Senegal and Mali
* Indoneasia and Monaco
* New Zealand and Australia
* Ireland and Côte d’Ivoire
* Norway and Iceland
* Venezuela, Ecuador, and Colombia
* Luxembourg and the Netherlands
* Slovenia, Russia, and Slovakia

This is where this space helps.
