I know it isn't a core feature of the game.
But the default colors (fortunately we can change those) of the players' factions are sometimes confusing.
Notably, the Lawyers, being clear grey, are often mistaken with those who don't have factions, being white.
On the other hand, the family & the brahmins boys are both kind of orange, so it isn't much clear to know which factions those guys are members of.
I don't have much issues with the colors used on the worldmap, but some tweaks could be welcomed for their names and their contours.
I am sure there are more colors available to make those four factions (five if you count not having one) more recognizable.
(no need to change the colors of those combat armor NPCs)
