Started a fight in the area between Gut's room and Ragzlin's room. At first only my druid was considered hostile because she was the one who initiated aggression on the gobbos who push the guy into the pit. So for her, all the nearby goblins are red; for the rest of the team, a little way out of sight, the goblins are still yellow, until my other party members join combat.
Once everyone is all joined up, a few of the goblins bunch up, so Astarion sees an opportunity for some Void Bulb shenanigans. He tosses one and ends up catapulting FOUR enemies into the spider pit at once. Strike!
Only thing is, now the goblins in the pit are yellow again, as are the spiders. At least, they are for some of my team, but not for others. The goblins were obviously hostile to the spiders, and the spiders to the goblins, but by the middle of the fight I simply could not work out who was hostile, friendly or neutral to whom, which made planning turns pretty awkward. Especially when Ragzlin yeeted Lae'zel into the pit as well.
No idea how this can be made clearer with the three-coloured system, just pointing out a kink. It was hella fun, though!
