Simply changes the blue colors of the Light, Heavy, Shield (Including the Ballistic Shield), Taser, Grenadier and Dozer to black.
Blacks can seem a bit weird (greyish) on some maps, especially darker maps.
Nonetheless, imo it's enough for what it's worth, since I'm not an actual modder and the way to actually do this mod was way more complicated than it first seemed to be.
Additionally, there's an option for the Light, Heavy and Shield to have yellow tinted goggles and face shields, as a separate file. Thanks to Yamanu for the suggestion.
Zip Folder is included with every enemy seperated as a .pak so you can choose.
