Cool Phruby, I'm glad to see you continuing with the Microman figures! Aayla definitely lends herself nicely to micromanification (or would it be microwomanification?)
For her paint color, off the top of my head, I would use Ultramarine Blue mixed with a bit of Blood Red (just a tiny drop) and maybe a little Shadow Grey (all of these are Games Workshop brand paints, I can't remember if you use GW paints or not though).
I would recommend painting her top direclty onto the body, since her shirt was pretty tight in the film, I think that dremelling out the figure's chest piece would not work very well.
I can't wait to see how she comes out!
