It's the Four Color Theorem.

And well, it's actually mathematically proven, but not for maps with disjointed regions that need to be colored the same, such as Alaska + mainland USA.
(In that particular case, it's not too difficult to resolve, but you don't get a guarantee for it.)

The map in the post actually merges such disjointed regions, though, so it absolutely should work there.
