Color suggestions for a dark chocolate paint for a vanity?

bathroom update keeping the old vanity and repainting cause it is solid wood and has lots of storage.don't like construction of newer vanities...wall is going to be a light calming blue and want to paint the vanity a chocolate brown.with a high gloss latex.Usually buy paint at Lowe's sherwin williams and benjamin moore....don't have a home depot near...any suggestions for the vanity color that u have personally used...the wall color we think will be benjamin Moore's tranquility which is a very pale blue...should we paint with a roller and should we put on polyurethane and do u think brushed nickel pulls would look good.faucet is going to be brushed nickel and light fixture in brushed nickel.
