Great idea.
If you did not have the black roof, you would have more color coordinated options. Ask a few women that are good at picking colors.
With the rest of the car...black is your best choice IMO
I found OEM clips on a 65/67 dodge coronet/polara. Nice factory clips that fit the "newer" 70's emblem studs perfectly. They have a small hex-head so easy to gently tighten with 1/4 drive tools.
