Ok, I've had this idea for awhile now. So.. When you have a glass color you have an option in your glass colors menu to make it so when you join a team your glass color is also the color of your team. If you don't have the color of your team it randomly chooses one you all ready have. So if you join blue you get blue glass color, BUT if you don't have the color the system automatically chooses one for you that you all ready have. You can toggle this option on and off.
