There are several paint chip chart websites. The colors don't always look accurate, but others have the color names for the different Chrysler Corp divisions, plus a multitude of listings for different brands of paint. All within a Google search. DuPont and PPG were the major brands, usually, back then, but the older paint formula numbers might not work anymore.
Some of the listings, fwiw, also have the "other pages" for the particular model year. With paint stripe numbers, interior parts paint numbers, trunk paint numbers, etc. Not just the exterior color paint numbers. I also found a Sherwin-Williams all makes paint book for 1978 vehicles.
For verification, the Paint Code should be on the lh inner fender area on the Data Plate.
Nice looking car!
