Team colours in Lockdown seem to be in a state of constant flux and why that may be pretty to look at, it can get confusing at times. I cannot even count the number of times I get used to playing one colour and then in one game the opposing team gets that colour and for the first minute or so I occasionally mistake my teammates for enemies and enemies for teammates.

My suggestion is to fix or lock the player's team to a certain colour that only shows up for that player's team and the opposing team gets fixed to a different colour. For example, when a players plays a match in lockdown his team colour will always be blue and the opposing team colour will always be red. The same would be true for a player from the opposing team, they would always see their own team colour as blue and the opposing team as red. This may take some tricky client-side coding but I have seen it effectively implemented in other MMOs.
