Google images is your friend there are tons.
the exposed carbon looks good on all colors IMO. the ashen gray looks good on certain colors. It does not look as good to me on red, orange, ashen gray, yellow. Looks decent on black, white. have not seen it on silver yet but it might look good becaue there is still a ton of contrast.
on a black car I would be conflicted. all other colors I would roll the exposed carbon.
