It's staying light out later, so why not embrace your dark side and try cloaking a room of your home in black. From mid-century modern to traditional romanticism, there really isn't a style that black walls don't work with. White trim helps bring light in despite the dramatic hue, and pops of color in seating, pillows and rugs allow life to shine through. If a masculine or hipster vibe is more of what you're looking for, keep colors in the room other than black or white to a minimum and add interest through quirky art and accessories.
