Hello,
I am red/green colour blind.
There is an option in overwatch 2 to change the colours on the UI/HUD elements including player outlines. However this does not extend into the actual characters effects from abilities, that are still red.
For example when an enemy Tracer uses her blink ability the effects are subtle and red. Another example is Symettra where her turrets when thrown are given a red trail, usually helping other players see where it is going, however for me it makes no difference to not having a trail at all. Is there a fix for this or just something the game is lacking from being accessible to everyone in some manner regardless of disability?
