No you can its the name of the file. If the file has a space it needs it. The armor gets textured but it can't be dyed like leather. When I dye it the item you hold gets dyed but not the armor texture that gets worn.
The armor itself is colored and can be dyed but when the armor is worn the colors don't transfer. I believe I need to make a custom armor renderer. I just don't know how to do that.
