The interior section of the side mirrors autodims just like your rear view mirror. The outer perimeter does not dim which is why it still has normal coloring. It looks like that side mirror is stuck in dimming mode during daylight. Maybe try doing the two scroll wheel button reboot to see if that fixes it? I forget off the top of my head if you can turn autodimming off in the settings. If you can try toggling the autodimming to see if that fixes it too.
