Charcoal walls, black crown molding, Burgundy wood floors?

We have a 400 square foot family room upstairs with 4 walls and 3 huge windows. We want to have the walls painted dark charcoal, black crown molding and Burgundy wood floors. Has anyone did something similar? We have a dark purple sectional couch that sits 10 people, we have a black coffee table with marble top. We are going to have a black iron wine rack with gl on top. I am just curious at to how it will look.
