I know you guys are working hard on trying to make lightning look better in the game.
In 1.19c it appears you hooked up some code that does ambient lightning effects on units stationed in various environments. Frankly, it looks horrible, like way over-done. If I were you, I'd tone down the strength of the lightning by around 70%, so that the lightning doesn't automatically "replace the color scheme completely" like it does now.
Examples:

Sovereign in fallen territory - orange as hell:

The lightning from the kingdom/grassland environment seems much better done.
