Swarms should match the faction color!

That would involve making each nation's swarm an independent item, I think, and they allready just got changed anyways. More color choices sounds cool, but is this how we want it to be designed? Not personally.

-1. Weapon appearance should be used as a way to identify the weapons, not for personal expression, nationalism, or anything like that.

I am open to the idea of letting people customize the color of their ship's engine plumes (and, in future, headlights).

I rather it match the color of your ship...
