alternate team colours.......

Who here has seen some of the kewl alternate colours for the civs? For example, the Zulu civ is usually yellow, but if you play as them and choose the egyptians as an opponent, your team colour will be black! I tried this, it looked amazing.....another one is the persians losing their lime green and replacing it with teal if your opponents include the greeks. and once, i even got the babylonians to be red, i can't remember how i did that one though........if there are any more that i missed, please post them here, as well as how you got 'em, k?

just look in the editor! they're all in there - each civ has a default color, and a unique color
