From what I have gathered the knobs should be maroon, and the bright work is mostly polished stainless steel. It is possible to have Chrome bright work or black knobs? yep. I would guess it is possible to have mixed color knobs in a vehicle. Say they had installed the factory chrome wiper knob, they wouldn't spend the time to pull it to match the maroon dash knobs. Like Woody said the Command decision is yours to make. For what it is worth in my 52 all the knobs are maroon. The wiper, dash, vent, and door knobs all match.
