Player vs Enemy AOE coloring

[Sinnder]

It would be very helpful if there was even a slight variation in AOE color between group or enemy effects.
As it is currently, a tank is not sure if he is pulling a mob out of a helpful AOE (Consecration, Rain or fire, Ice Storm etc) , or the same spell that is killing the group.
Even a slight difference so we can tell if it is beneficial or dangerous would be GREAT!
