I actually don't mind the colour variation anymore, now I've got used to it I like it quite a bit. Granted, it's not accurate, and I would of course prefer it was all one colour, but for me it's still an awesome looking figure.
It's not even that bad a variation in hand really. It's also difficult to tell what the overall colour should be since in the game and in promo shots the colour varies too.
If DCD had used the same colour for the boots/gloves/cape, I wonder which they would have gone with.... Personally I think the blue works just as well as the black, so I'd have been happy if it had been made in either colour.
