So I can believe these are phenolic resin. Only a very thin outer layer turns cherry red with age & exposure unless heat treatment is used to drive the color change reaction.
For your first photo, I’m not sure. There doesn’t appear to be any amber undertone, but color photography that is underexposed like in that picture can mask a lot of features.
