Thats definitley got a flamed maple cap, which the IB6S doesn't have but i assume you knew that. The bust is unusual, but not impossible. If you were in Australia, I would point you in the direction of U-beaut dyes, which are water based. I've seen a couple of greeny blue bursts done with those dyes. The purple can just be mixed by using the colours. The finish is just a satin finish so either a satin based acrylic or poly spray, or if you use shellac or tru oil, just don't sand to full shine.

Thats the best I can give you at the moment with the time that i have tonight.
