The colorblind mode is becoming a very frustrating issue. One that could easily be solved on your end. Let me change group and alert colors in the colorblind settings and I will (almost) not be at a disadvantage to other players, only because of my color blindness. This issue becomes especially significant when playing a support hero, because the group/alert/hurt allies colors are almost identical to me, regardless of which settings I pick. So it doesn’t matter what color my team is when my GROUP automatically becomes the same color as a wounded ally.
In short; just let me change the group/alert colors. It is such an insignificant change on your part that it really becomes insulting to your players with color blindness that you don’t simply add this option to the already existing colorblind mode. If you for some ungodly reason decide not to do anything about this, I strongly urge you to do something about it for Overwatch 2.
