Well, I was actually thinking about the blue, red, and black shirts they wear. That's three colors to have to worry about. And throw in the color of pants to boot. Have they found a way to solve the color variation issue? Or do they solve it by standing 90 feet apart? ;)

I would hope that the grey shirt will be adopted, the only problem is, all officials will have to spend money to get them. Also the vendors will be flooded with requests for those shirts and will have to place numerous back-orders.
