I need help on how to match a tux to my prom dress?

So I wasn't planning on going for a print but I bought a cheetah prom dress. It actually looks really really good :) however now my boyfriend needs to get his tux and I need help with what color he should get!! also what color should the corsage and such be? The dress is mostly a deep goldish color with black and dark brown and some cream/beige.
