An alternate to red for planets belonging to players binded by NAP.
Maybe the same interface than BT warning you are about to break a treaty. Do you wish to proceed?
Very often honest mistakes happen, someone alerts a planet from an ally, someone takes it by mistakes after which both legions have to sort out things.
It could be an alternate color to red.
It could be a warning upon attack like when we are about to hit a NAPed player.
Sometimes officers can catch up fast and go .. no no no.
I would like a game feature.
