I'm not blind. I play on a not-so-great laptop where I have to set the resolution to 800x600 to make it look somewhat decent. And this isn't just for that reason. It's for people to spot others easily even when they have a great PC. For example, if there's a sniper and wasteland, but you can't see him because he's laying down somewhere and not moving, this would help you spot him WAY easier.
And why would it be such a hassle checking what team you're on constantly? It takes two seconds. Bring up the scoreboard. If you're on red, your enemies are green. If you're on gray, your enemies are red. What's so difficult about that?
And bayzo, you need to know how to extract the files, convert them, edit them, do VERY SIMPLE hex editing, and convert them. If you don't know how, there's a thread somewhere in the modding section that shows you how to do all of that, but the tutorial is for weapon camos. Just follow the steps, but do the character textures instead.
EDIT: Also shadow, I'm making this because chams and other hacks get detected and patched. This won't since we're just changing the texture colors. Sure, you won't see people through walls, but you can spot someone from a mile away.
