Cocolate Brown Blue And Black Tuxes?

Hey i am having a wedding in october and am thinking about using chocolate brown and blue. Having the maid of honor in light blue and the bride`s maides in brown. The same goes for the best man and groom`s men, having the best man in the light blue vest and tie with a white shirt and black tux, and the grooms men with the brown tie and vest. My question is, would having a black tux with those colors clash? Would it be one too many colors? Help!
