Black And White Bathroom Rugs What Colors Work As Accents For Black And White Tile Bathroom?

What colors work as accents for black and white tile bathroom? - black and white bathroom rugs

I moved into a new apartment, which, unfortunately, a wall of black and white tiles. I like Zen bathroom is not so ideal. What a beautiful color (except red) works well for accessories such as bathroom shower curtain, rugs and other accents? I thought, smoked amethyst or plum?
