Colour Pallet/ Art style revisions

I was thinking that a black silver/white and gold colour pallet could run throughout the games artstyle not only be used as a means of adding higligts of colour to Caruso's attire, also be used on the games UI  for example as a means of highlighting various important aspects at any given time... the motiff of black white and gold could be used on important in game objects and enemies and certain important objects highlighting against the other used in the game... The idea would be not to only use black white and gold for the games colour pallet, but use it as a motif that runs throughout the game- highlighting it's important aspects... restrained use of Gold would need to be utilized for it to be most effective and not over baring.
