I had, previously, put a black wash over some Nolzur/Wizkids figures to see if it would make life easier to paint.
Anyway, for various reasons I fished one out of the box and thought: here, how would this previously black washed figure take the new Contrast paint
Well...not terribly, no.
The Dark Angels Green, for example, goes on REALLY well over the black wash. Predictably, the lighter flesh tone does not. Alas, I'd already lost a bunch of the facial detail from the wash, so the experiment ruined the verrrry soft detail here.
