Ah, I see what you meant. If other people hit with their bow and arrow, and they are in your team, it is not coloured if I recall correctly.
Come to think of it, this is especially annoying when you are walking with someone in your team. If they get shot and hit by an arrow, you can't see them get hit very easily because it isn't coloured.
Excuse my initial misread.
The right man in the wrong place can make all the difference in the world.
