The forum swallowed your post I'm afraid. Damn bugs! Can you repost it?
The colour scheme is the blue and white of Eldaronline, btw. The CWEO Dark Eldar, Outcasts, Harlequins and Exodites wear colours according to their own tastes, so only the Craftworlders wear the blue and white into battle. You might find pennants and banners of the CWEO colours in the other groups though.
