Hi Garner. Just one last message to say thanks again. You have been incredible help to me here and I now have a pretty good understanding how it all works.
Just in case you fancy a peek, here is the working code project on Github which assigns a Team and Colour material to each player when they start the game. Its very basic right now and needs work before it can be a proper game, but this is quite a nice starting point.

Much love and respect for the helping you are giving people here.
