Too bored to write an answer, but you might find something at http://sleague.apolyton.net/Guides/sldt_flags.shtml. I know two clicks from the Scenario League home page is hard to do. C'mon St. Leo can't you make it easier!
That was harsh. It was a knee-jerk reaction to what I felt was a lack of appreciation for Dan Scheltema and St. Leo. In retrospect, I can understand wanting a quick answer without having to dig a lot. Please accept my apology.
Is this the pic you're after? It's in the link above.
Here this will help. Attached is an item from an Allard comp, but I think it might be scottF's? I dunno. Anyway I have edited it to show what you need. there are 3 colours related to a civ. 1)City name colour, 2)shield colour, and 3) 'stacked' units' secondary shield colour. This attachment depicts the flag area at the bottom left of cities.gif.
