I was thinking of how to make nights seem colder and bright day seem hotter, like in most TV's where you can change the temperature of the overall image.
I know LUT could help with this but I wanted to avoid dark parts of an image (like shadows) looking bluish in plain day, like when using Crossprocess the shadows look deep purple.
Perhaps something like Ambient Light's Adaptation feature could be used to achieve this? Basically it'd be like this:
Overall image is dark --> cold color tone
Overall image is bright --> hot color tone
