I'm new to Eldar and I have been working on an army list, I have read a few things here but I would like to have a genreal consensus, Does anyone paint the aspects in their traditional colors anymore or does the aspect match your army's color scheme?

I like a uniform look to the army, but I'd still work some of the aspect shrine's color into the scheme.

Banshees are pretty easy, just add a bit of bone.
Any green goes well with scorps, as does a touch of yellow or orange.

Well, you get the gist. It's really all up to your personal preferences. I've seen it done both ways, and I find no fault with either.

I paint mine totally to suit my Craftworld. The first reason is because it fits in with my fluff more, and a colour deviation would stick out far too much for my liking.
