Hi,I'm fully colourblind (achromatopsia) and basically the game is in black,gray,white for me. I played for like 2-3 weeks now and really like the game. But basically I can never tell who's an ally or enemy,can't see anyone unless they move...

Every time I'm supposed to hold an angle either enemy's on left or right of my crosshair but not on it. Whereas I've seen alot of players one tapping enemies? So here's the question...how do I get a crisp aim?
