Advance to 4th job Kaiser, default transform armor becomes... black?

From what I heard, you can't change armor from black, it'll always be some shade of black after 4th, and I've done a few coupons and so far, my armor has never become anything that isn't black.

Yeah, sadly that's the only problem. It's just different shades of black and the only real change is the Dragon Slash color and "Flames" behind you from using Giga Slash in transfig.
