This is the same method that Paul Reed Smith uses to get those fabulous colors on their axes.
(BTW, you've GOT to see their Al DiMeola sig model: Different parts of the body are different are different colors/stains, can not imagine how hard it is for them not to run together at the margins!)
Alembic's usual practice is to shoot several clear coats, then apply color, then with more clear over it to finish. This way if you ever want a refinish, the wood was never stained as the color was suspended between the clear coats. Both of my colored axes are shot this way, and they're beautiful.
But this is a really nice piece !
