Even body color (white) would be better than chrome. I'd try the black first, then if you didn't like it, paint them white. I dont know why Jeep insisted on putting chrome bezels on Wranglers when nothing else is usually chrome on them.
At least Jeep did not put any chrome on my 99 Cherokee sport. It is either black or body colored (dark green). The lug nuts are chrome, that is it. They would look better black.
