All transparent minis should first be undercoated with Army Painter Anti Shine transparent matte varnish, so that the paint has something to grab on to. This part is Key.
After that, I find that simple is the way to go with the transparent Bones for best results.
This one was transparent blue to start with, I gave it a wash with Army Painter Quickshade Blue, drawing off the excess and when dry, a very careful corner drybrush with an offwhite with a turquoise tinge.
