In my original commit for ticket 91216 I was using orange for aggroed friendlies and magenta for projectiles
This seems to have been changed back at some point to red and yellow respectively.
The use of red for both aggroed friendlies and enemies has been causing confusion among non-colorblind users despite the different symbols, and should be changed to something else.
A conversation on discord suggested:
aggroed friendly/neutral: yellow
enemies: red (leave as is)
projectiles: magenta (return to original 91216 impl) or something similar (maybe pink or light purple, so its more visible on a dark background)
