WAF Help Please

I have spekaer cables that have a silver/white jacket. This looked great in a room where the main floor treatment was a white colored rug. I have now relocated my system to a room with dark brown hardwood foors. The white/silver speaker cable jacket stands out. I really like the cable (Crystal Cable reference), and do not want to switch.

Does anyone have any suggestions on something I can (e.g.) buy at a hardware store that I can surround the speaker cable with that will make it stand out less and yet won't harm the sound?

Thanks in advance.
