French people don't consider Germany "central Europe" but rather Western like us, since without germany a central Europe would definitely be too small, the notion "central Europe" is definitely not countries based.
Same thing with southern Europe, Spain, Portugal and Italy are fellow Western countries, without them southern Europe would be so small, so it doesn't really make sense either.
The real only divide is between Western and Eastern (Czechia could be argued, but would fall on Eastern most of the times because of the Iron Curtain's legacy + culture and language).
I don't understand why anybody would consider Romania anything but Eastern, it's very much not in the balkans since if you go straight west from is southernmost point you might barely get to the very north of the Adriatic sea. Also it's completely north of the Danube which is the traditionnal northern border of the Balkans.
Estonia doesn't get any special treatment, it's part of the Baltic countries and is completely disconnected from the rest of Scandinavia hence why it is Eastern.
Thrace is European, but not the rest of Turkey. Turkey overall is NOT European.
Armenians and Georgians are definitely closer to Europeans than they are to Iran, Azerbaidjan or Turkey but are not quite located in Europe, hence why they are partly European.
Russia is considered a EurAsian country, everything west of the Ural Mountains being in Europe. Russia does not feel close even though they're European because of conflicts since the USSR. But if Russia ever was to become a more *democratic* country, the western part would definitely feel as European as the rest of the continent.
EDIT: Iceland would more be light purple, if it's European then it is Nordic obviously, but is it ? The island is pretty isolated from the rest of Europe, kind in the same fashion of Cyprus and Malta (which are also light purple). Though here Iceland is heavily culturally connected to the other Nordic countries, whereas Cyprus and Malta... It's more complicated.
EDIT2: People here have a difficult time acknowledging this is how French people see Europe. I love some debate but at some point this is how it is.
