I've been reading over the IC and the Kings Char Sheets, but I'm still a bit unsure

The policies that I have determined are:

Black is World Domination, Red is a "take all comers", Blue is a group of trolls, White is VENGEANCE WILL BE MINE, Green is Switzerland and Orange is sinister and aggro. Did I get that right? Also, what is Yellow's deal? They're the only one I can't seem to get a handle on policy wise.

EDIT: I bit the bullet and decided it would be in Alex's nature to have joined the Fanged Rangers, polite and considerate after all.
