I just checked my local game store and guess what, they actually had GW paints. w00t =).
Correct me if im wrong, but the lizardmen team is boxless because it's another company that made them. Same with Amazons and Norse I'd believe.
Anyway, here's what I had in mind for my Skaven models. I found some pictures from the Resurrection tournament and these models just blew me away. Could anyone tell me what colors I would need to do something similar? Thanks.
Here goes nothing...

If that didn't work, then here is the URL:

Please take a look.
- edit - Also, could anyone do a rundown for me on the base color coding system? Ie. what colors go on the bases for blitzers, throwers, catchers/runners...
