My master bathroom is quite small. All of the fixtures are white. The vanity has a granite counter top and white doors/drawers. The mirrow above the vanity is the same width as the vanity and is trimmed with a 3 inch wooden frame a dark chocolate colour. I have a large picture in the bathroom and it is framed in the same colour frame as the mirror.

My question is, I would like to purchase a wall mounted cabinet to put above the toilet and it comes in both the white and the dark chocolate colour. Do I have to match to vanity cupboards or can I match the other dark wood?
