Copy it if you like. I find dwarf\'s look crappy with any bright colors like yellows and stuff. Just doesn\'t suite the models or the army feel by my reckoning.
Paint one model in a scheme you\'re thinking of. Maybe paint a few of the shields in different schemes and see if anything sticks.
mine are much like kroms' except they are citadel vermin brown on the trim and left sleve and blood red on the right sleeve. realy like youre scheme squig hunter.
i really like squig hunter's theme. they look very cool. otherwise, i'd like to see a theme of a dark, saturated red combined with a diluted green, like catachan-ish. but don't make it too bright. it'd just look glary. wouldn't you think?
I wouldnt go for anything bright. It just doesnt suit dwarfs.
Apart from that, any colour can be used in my opinion. If you are in doubt, try out a few things on the model itself. That works the best.
