Believe it or not, that color blind option will be the best update (for me) since day one. I've STRUGGLED with the radar in certain areas, especially PvP maps. I'll have to look a different direction to change the background color in order to see the red pop up, at all. I didn't really mind getting blues and purples mixed up and not being able to tell the difference, but the radar was a fairly big issue with me.
Thanks color and audio team. You guys rock!
