SFM "WashGreen" Color Correction

Digging into different SFM leaks, there's a pack of color correction files called "washgreen" with variantions numbered by quarter percentages (100, 75,50,25)

I slapped these into l4d2, and seemed like they match some of the shots of the intro, although different shots seem to use either different washgreen variants in each shot, and or used different light and fog settings in the maps for certain shots.

For this reason, I cannot 100% confirm these were used in the intro aside from them matching what was used in the intro to L4D2, but a lot of these seem to match certain shots of it.

This mod replaces multiple campaign color corrections with various "Washgreen" color corrections

Dark carnival uses washgreen 50
Swamp fever uses washgreen 100
Hard Rain uses washgreen 75

currently Dead Center and The Parish aren't modded, but that may change in the future if I find spots of the intro that seem to possibly use these color correction files
