The louvered taillights were only equipped on super bees that had the rubber painted bumper option and they were painted a satin black.
They were standard on 500 and R/T and had a 3 stage finish which consisted or argent on the main housing, silver on the beveled edges, and black surrounds around the lenses.
Here's a collage from Nacho showing all of the different 3rd gen charger taillights and their finishes.
