Curtains for White and Black Wall?

Please I need help with choosing curtains. I have an opposite wall which is painted white and the other wall has a black granite wall paper. We already have blinds, but find the lounge too cold in the winter so I bought a "mink" color curtain, but it doesn't look like it is going to fit with the colour palette. I have black leather sofa, black dining, a bay window, and dining doors.

Please what colour curtain do you think will fit these walls? Do you think mink is a good colour for it? Please I need you knowledgeable folks to help. Thanks a lot.
