I'm on console and you can turn on enemy attack colours in settings. The default is red but you can choose to change the colour, brightness etc

So many questions about stuff that "addons do" where it turns out it's vanilla game settings.
I always wonder why ppl are not simply pressing ESC, click on settings and scroll thorugh the very short menus there first?
Less time invested than writing a forum post, and waiting for answers

back to topic: Addons cannot color that incoming or outgoing aoe effects differently, it's vanilla UI settings.
Bad and friendly effects

I recommand to color bad ones pink as you can easyily see those on lava and other red undergrounds.
Default is red, which makes it hard to see it.
