The city of Wellspring. I have no idea why they mismatched the lighting from inside the buildings with the outside. When you go in the garage the inside has a color grading post processing effect that makes all the ambient lighting blue. If you look to the outside from inside the garage the outside has a blue mood, almost as if was night outside. Next, the Mayor's office has god rays that completely mismatch the outside. The sun outside is not shinning in that direction. In addition, why is the light so orange inside? The sky suggest it's lunch / noon time, not sunset time.

This isn't a mistake that breaks the game, but it breaks the immersion effect. I can't say that this mistake was caused by the game's engine used or if it was an artistic choice. Color grading is about atmosphere and mood setting but mismatched like this  feels very wrong.
