Using Google Maps this is really not easy, as @oezi said you would need to build overlays of every country you want to color, which frankly sounds like a mess.

But if you don't need all of the functionalities of Google Maps, perhaps you can use a Map Chart from the fantastic Google Chart Tools (aka Chart API). You can check and tinker with a working example of a Colored Map (among some others) in the interactive Chart Wizard

2017 UPDATE: This answer is quite old and as such the Map Charts API has been deprecated by Google. You can use the Geocharts from the Google Charts API instead:

Hope this helps!
