Welcome to Librarium Online!
Well, it depends on how good a painter you are. In my experience, tau look terrible in human camo schemes. basically;
White & red: Hard to paint white but looks really good if done right
Camo: I hate Camo on Tau so, i'd say no
White & Black, again, if it's mainly white it'll be difficult to paint, In my opinion, it doesn't look as good as red and white. If it's mainly black then the white may stand out too much. I'd recommend red or blue.
Hope I helped mate.
I agree that human camo on Tau look too "busy." The models almost look "dirty." Not sure why that is.
Speaking of dirty, though, you could try a minimal "light" scheme and, like Bruno Rizzo did, "distress" the armour with streaks, rust and chips, letting THEM do the talking. When/if I ever do a Tau army I intend to rip off his scheme. Looks awesome.
Do you have a link, Canew?
thanks i think ill try white with red. if it works well ill post a picture of it
it's also easier to get good shading and highlightings on red rather than black
