Just because it was used on a different brand car/truck doesn't mean Ford, Chevy MADE that color...
There are GM-Ford- Versions of Hemi Orange, Inviolet, Etc...
In fact, I read somewhere where the SAME paint was used, just called a different name/Code.....IMO, painting a car with another Color than what would have been offered as original isn't like dumping a SB Chevy in a Cuda...
