SS/B Barracuda project

From what I understand, if the local Car Dealer sponsored a car, they usually also put their License Plate Frame on the car. Have not found many good pictures from ´68-69 of this, but my observation about the License Plate Frame is, Chrysler Plymouth usually used blue color, and Dodge red, if any color was used on the frame.
When I´m going to restore this frame, I was thinking white or polished aluminum letters on blue back ground and frame polished aluminum.
What do you say/suggest?
