Green and yellow crosshair colors blend in too well on some map angles. For example, ascent has several locations where it's too bright and you cannot see a bright crosshairs color. Haven has several angles where you're either looking at a wall on attacking side or radiant boxes that blend in too well. I don't use cyan but I could only imagine how rough that is on icebox. Acent is really my problem here, the sunray is too bright and everytime I play there I lose track of my crosshair because of lighting.
