Four is the magic number when each "territory" in the map is a single "blob". In many cases, this cannot be guaranteed. An example is political maps. As specific examlpes, there is a "blob" (a single vilage) of Germany completely surrounded by Switzerland. This wouldn't actually necessitate a new color, because Germany and Switzerland abound anyway. But states (Cantons) inside Switzerland are more complicated, and similar things will exist elsewhere.
