I'm a chemist and I answered this in post #10.
This is incorrect. Paints are made up of many chemicals and may be a mixture of pigments. Red (like any color) can be a mixture of chemicals and pigments to give the exact color desired. As I already said, seems most likely that schwinn had a paint formulation in the mid '50s that was prone to chemical ageing where the pigment in the red region of the spectrum degraded/decomposed leaving other pigment(s) that did not decompose, which results in the gold color you are seeing in all the pictures. Again, use logic. How can you be seeing a gold base coat UNDER decals?
Are you an Automotive paint chemist?
