@Nameless - Not concerned with the normal DA colors. I am actually going to be playing this army. It will be fluffed as a vanguard of the Raven Wing (so yes the vanguard vanguard of the DA) Yes the armor and the bikes will be the same color.
Since I am going to play this army, 36 bikes, I want the colors to be striking and eye catching. 6 of the bikes are comming from Scibor and they are functioning as a command squad.
The list in itself is actually weak, but I am going for best paint in tournaments. I know it doesnt take the level I am going for but I like to blow people away

. Out of 15 or 20 fairly large tournament I have participated in here in the states I have taken best paint 12 times. I want to up the anti a lot with this army.
@Skya - I see what your saying, and if it were not a battlefield army then I would agree with you, I love limited pallete. So if you were walking around a tournament and 150 or so armies were sitting around what would draw your attention most? I say this because sometimes the best painted armies do not recieve much attention.
