Thanks for the praise. I guess I wanted to have each commando have their own appearance. I took inspiration from Delta Squad's armor. There isn't much to go by, because the books never really show you precise armor colors beyond flat white and black stealth armor.
I wanted to go with the individual armor colors because this was during the mid point of the war. I'm not sure if phase II clone armor had been distributed or not. I also don't think the commando armor changed much during the war appearance wise, but more technology wise. As it had a slight vulnerability to EMP during the opening months of the war.
The only one with a confirmed photograph of armor color is Niner - who wore the dark blue/black armor.
Hasbro messed up and packaged Niner as Fi. Fi doesn't have the four rank dots on his chest, but Niner does.
To me it only made sense to give Fi red, because he is the Medic/Sniper for the team.
