I know this hasn’t been fleshed out yet, but I was thinking. Instead of having generic colours (red,green,blue) for clothes, clothes could be died a specific RGB code. That way if players were trying to infiltrate using a disguise, they would have to guess at what colour was being used. Assuming groups didn’t choose an obvious colour like pure red, on close examination you would be able to tell if a uniform in genuine or not. Now I haven’t decided if it would be good to allow picked up clothes to be examined for their code so that players could kill to get that information, because that would invalidate groups trying to keep their code a secret (once you find the code, you would always have it). Rather, once you have gotten a hold of some clothes, you should be able to put it next to the clothes creator and move sliders around until you find a colour that is close.
Also, I think there would have to be some sort of filter on the clothes, so people can’t just take a screenshot and then use an external program to find out the exact colour.
