Kal Skirata's armor is sand gold (metallic), with a jet-black (probably satin finish) visor trim, and red sigils on the helmet. No claw marks, from what I can find, and I've been making extremely detailed notes on all of them.
I'll check on Ghez Hokan's armor when I get home, but I think it was red with grey trim, not the other way around. He also had a red jacket that he wore sometimes, and a lightsaber.
Walon Vau's armor was all black, including the bodysuit. No red on it, no matter how kickass it might look. Someone in Bloodfin Garrison did an awesome Vau, according to Karen.
Bardan Jusik's armor is more or less a forest green color. Check it out here. It's got Karen's approval, too. Page six has finished pics, and a copy of Karen's e-mail.
We've got a Rav Bralor/Vhonte Tervho over here that's really accurate already.
Ordo wears dark red armor and helmet, probably with a medium grey undersuit, and Mereel wears dark blue, and probably also has a medium grey undersuit. I'll ask Karen about the other Nulls, since we can assume that they all had regular Mandalorian armor in addition to their Clone armor.
Those are all the EU Mandalorians we know of for whom we have no visual reference but at least a decent amount of written reference, but if I think of any others, I'll let you guys know.
