The cabinet (thankfully) is dark brown, but not nearly black as the photo shows.  It matched the vanity perfectly.  We were impressed by the quality and the fact they even included a little tube of wood glue for the dowels.  We always glue the dowels when we assemble IKEA furniture but IKEA doesn't include glue or even suggest that you do it.  Which is stupid, because it really makes the pieces stronger.  The addition of lights inside (we'll use battery-powered puck lights, unless we can find a way to sneak in IKEA cabinet lights) would make it perfect.
