These are the hidden textures from the Uniform Locker texture. Luckily, there's a RED and BLU version of the Uniform Locker texture, so there's RED and BLU versions of the alpha textures.
The Spy is the most incomplete, his mask was a quick-edit job in Paint.NET.
The Pyro is near complete, just some texture oddities.
The Demoman is the most complete, having a much brighter color choice.
