I recently got some kroot and finally realized how good they are! But I didn't want the green coloations. Here is what I was thinking
My tau layout is
Skull white (sept marks)
and for highlights on lenses, grenades, ect:
Icy, Enchanted, and regal blues
and for my kroot I was planning
Tallarn flesh foundation
Ogryn skin wash
Leather and bits:
Terracotta (3 parts Vermin brown mixed with 1 part blood red)
Tin bits (DUDE, KICK BUTT DARK COPPER)
and the above tau colors to match on armor and war paint.
The Black Hand is watching...
BTW, I hate your GK termies.
