I bumped into this nice overview of official country logos, mainly used for international promotion along the lines of “we’re nice, come visit us and spend money”.
Well-designed mostly, but it does strike me that they’re often very, even extremely colorful and full of flowers, hearts and sunshine. Apparently the flower is one of the most powerful symbols for a country. I can understand that for Holland (national flower: the Tulip, and well known for it), but some of the others? No idea.
