Black walls will provide a dramatic contrast for almost any color of curtains. For a sophisticated look, you could pair your black walls with curtains in a neutral tone and a natural texture. For extra drama, you could choose curtains in a saturated jewel tone (red, blue, green, or purple). Or, for a modern monochromatic look, you could look for a patterned black and white window treatment. Consider what other furniture you will have in the room when deciding a color scheme for your curtains.
