How to remove Red/Orange filter effect in certain areas?

Hey Dudes.

I just started playing KF1 again after a good few years on a new PC because I wanted to max my last 3 perks but have noticed this aggressive red/orange filter tint that I don't recall which takes effect in a few areas and was wondering how to disable it as I'm fairly blind and it makes it incredibly difficult to play in these locations without taking on heavy strain and discomfort.

The first notable location was in Biotics Lab straight across from the spawn point there is the room with the stairs leading down and the red ceiling lights, the effect is localized to this room which is easy enough to avoid, however the next location was an entire outdoor map (which I don't remember the name of) that contained a dilapidated military base inside a jungle which made the whole thing unplayable for me.

If anyone knows of a setting, console command, patch or other solution please let me know.

Those are properties of the map's zones, zonefog properties. I don't know of any ready-made solution but it's certainly possible via a mutator (although you would lose the ability to progress vanilla perks). Otherwise you can edit the map themselves in the SDK and adjust those zones for better visibility.
