I noticed something with the CLR-BLU paint recently: It changes the color of many of the mech's base colors that other paint jobs don't.
I realize this is probably a bug with this specific paint job, but its behavior is actually something I'd like to see applied to other paint jobs. This could be implemented with the solid paint job colors using the scale slider; currently the scale slider does nothing for them.
Imgur Album comparing CLR-YEL and CLR-BLU for those that don't know what I'm referring to.
