Embrace the black. Consider it a temporary change in appearance, like changing your bar tape. When the black tires wear out, buy some more skin walls if you still dig that look. I've got black and skin walls on various bikes, and some frames look better with one or the other. My main issue with skin walls is they tend to look nasty after riding in the rain and are to ever get clean again. Also, there is limited availability in lightweight skin walls compared to all black tires.
