What is the files that dictates how the dynamic glow looks for things like rockets and explosions and their colors?

I'm trying to make the remaster look more like the imo superior N64 version where the flashlight is blue, the explosion lighting is softer (instead of that sharp blue light circle for ALL explosion vfx) and set the correct ones to their corresponding weapon. Night Dive did good with the remaster but they ruined most of the sounds and visual effects.

Which file dictates these?

I wouldn't mind making the warp portals look less bright and instead softer like they used to be.

I'm tired of the remaster looking so ugly.
