1. Paint the Walls
Get adventurous and paint some walls. In a big room, a black accent wall under a vaulted ceiling would ground the space. In a small room, such as a powder room, painting all four walls would make the space feel like a jewel-box—especially with metallic bathroom fixtures that would sparkle in any light. Either way, make sure to choose a matte finish—if the paint is 100 percent acrylic, it will be washable enough.
2. Paint the Trim
Another option is to paint the trim and the door black, especially if you have wide trim. This is a nice look with farmhouse colours on the walls, or thin pinks, blues and greens, which “are always stabilized by a dark black or brown," Schlotter says. If you have wainscoting, try painting that a glossy black with white walls. Add some black-framed art and on your way to an elegant look.
