The colour of Warpstone
I am about to embark on painting my skaven army (which I bough years ago but never got into building or painting it) and the discussion arose as to the colours of Warpstone.
I have been told that in the WFB universe it is crystalised evil, and that is exudes "black light".
It always seems to be painted green, but could it also be other unearthly colours?
I was thinking of painting mine a black base coat then layering of purple washes up to pinky purple hilights - is this against fluff or is it open to interpretation?
