Are you talking about the strips of plastic people put on the edges of the doors to help protect the paint from chipping when you slam it against something? If so it looks tacky (for me at least) when I see people use something that contrasts the car, it's like they're trying to emphasize the door gaps/jambs which is unflattering for a vehicle. I would suggest getting black since that would be easier to blend in with the coca or at least not stick out soo much as the chrome. The clear may work but may seem cheap depending on how subtle it is or will possibly yellow with time, but if they're cheap just replace when or if that happens.
