The Colorblindness flag causes teammates and enemies to look exactly alike by causing them to appear as rogue players. The identify/lock-on feature, by using right mouse click or pressing the
i key to identify players or lock on guided missiles, displays a generic 'Looking at a tank' message.
Colorblindness requires good communication with teammates to know their positions to avoid shooting them by mistake. The main difficulties are that positions may quickly become outdated and Stealth (ST) may increase the risk of mistakenly shooting a teammate. Another recommendation is to view the radar frequently, especially before grabbing a flag, as it allows one to have a general idea of the location and position of teammates and enemies.
