It’s a fantastic feature to be able to change the UI colors that denote friendlies, hostiles, and squadmates, but it could be a little better. Particularly, it would be nice if we could seperate shield flare colors from UI colors.
I.E. setting the enemy shield flare colors to be yellow while enemy UI elements such as motion tracker signatures and scoreboard data to be red.
Especially since all of these settings are specific to your own screen, I see no reason not to allow such color customization for these elements.
