1965 Dodge Dart Charger

After quite some time I finally got back the pie tin for the air cleaner.

First Picture is the decals that has been repopped.

Picture two is the factory pie tin with some paint off.

Picture Three is the reproduced ones I got made.

When I compare them the newest one seems like aluminium but the old one looked more chromed even if it not was chrome. I'm not sure what to do. Could there be differences over time how the aluminium take change in color?
