Lighting setup changes on a shot-by-shot basis to make the character in focus as appealing as possible. Movies and TV shows work in the exact same way.Interesting. I'd need to see the original cutscene again to see why they changed between warm and cool lighting.
This was also funny at the end:
Nate: That doesn't look anything like a bandicoot.
Elena: Have you seen a bandicoot?
Nate: No, but I'm sure they don't wear sneakers.
