If there are multiple enemy forces it would be nice if different enemy forces have different colors. This is important since different enemy forces could have different evolution factors and thus you think twice before attacking the evolution 1.0 enemy while you have no problem immediately attacking the evolution 0.0 enemy.

There's no way to set that per force in the engine, it's a single value used for all enemy forces.

Huh, that's brand new. I'll take a look into it - it would take a very different setup than just the startup setting I have now.

Do you know of any mods that use multiple enemy forces? I would need one for testing.

Yes. https://mods.factorio.com/mod/team_competition has an option to create one enemy per player. And I myself am also working on a mod giving each player an own enemy.
