While not my favorite suit, I still like the Mark V's combination of red, silver, and gold. Still a cool look, to me!
I don't have mine to hand right now. What parts are gold? I don't recall it having any gold pieces...
The one flaw on that suit up sequence was cutting away from Tony for the wide shot of the crowd going bananas. I reckon they could have done the whole thing in one shot, starting as it did with him getting the case at his feet, working around to his left, following the suit sealing itself around him, ending in the front with the faceplate going down.
