Jewel-toned shower curtains work well in dark bathrooms.
Your bathroom's main colors are dark, which means you're looking for a shower curtain that will liven up the space -- or a curtain that will further add to the bathroom's warm feel. A number of shower curtain hues will work well in a bathroom with dark brown, black or gray walls, so the selection should be based on your decorative style and the other accents in the space.
White
A shower curtain in a classic white shade is the sound choice for a black bathroom since this is the most common color contrast. A wrought iron shower curtain rod will complement the white curtain well, or you can use a white rod to create a monochromatic look in the bathroom. Variations of white, like cream or ivory, are ideal if the bathroom has silver or charcoal gray accents, and you can bring more attention to the white shower curtain by adding gray curtain ties or including a white flower arrangement in the bathroom in a gray or black vase.
