The old bearing showing obvious signs of overheating
The outer race/housing color is just typical corrosion/rust. I would be hard pressed to call that overheating--especially when the bearing lives within the knuckle as any of that heat would transfer directly to that.

Here would be an example of an overheated bearing:



Normally whenever there is drastic temperature change on things, there would be an oxidation boundary layer. Some people note this as "bluing" or where you would see a rainbow color effect. I'd be curious to see what the inner races look like, but usually these get destroyed when the slide-hammer is used to pull out the hub. But looking at your pictures with the inner race on the hub, it did not look overheated either.

This was the second time you had to replace this bearing?? What brand is it?
