Love this idea

I think silver would be confused with white... how about pink?  [e digicons]:karma:[/e]

Also, I think brown would be a good replacement for another color... maybe orange -> brown  

Would it be too much to ask for, for a setting so the game ignores the player chosen border colors and gives them to something you set during game setup, since there isn't a lot of colors left for custom factions , I usually end up with a couple of factions with the same colors after I made 3-4 custom factions.
This is starting to make the random faction thingie quite annoying, cause in some games I will end up with all the neighboring factions all having a yellow borderline, or something like that.

+1 about the faction colors, couldn't tell the 2 yellowish colors apart very well.

Colors need to be unique and distinguishable.

Ever try to play the game from a colorblind perspective?

To be more constructive, to help in my scenario is to offer more than just color. Border with the faction name or when you zoom out, a solid color of what borders you currently see as well as who owns them.

I approve as well.

Yeah in a recent game of mine both Krax and Gilden were present and they shared a common border.  My eyeballs exploded.

Thanks for the bump!

I would avoid the black. I can see them being confusing with the black grid lines. I don't mind the Forest Green. If anything, make Tarth into a lighter green to further distinguish the two.

I am hesistant of the silver. It's too close to white and could conflict Ythiril. However, I solidly agree that Kraxis and Gilden are too close in color. perhaps consider a Brown for kraxis?

Definately agree Resolin should be purple.

Definatley agree Magnar could be a Burnt Orange.

I won't be the one to go out and say Pink should be in there somewhere. Cause the runner up would probably be Tarth...

In addition, it would be nice if the border colors were a little more pronounced while in the cloth map view. There a bit hard to distinguish against the tan colored background.  

I like this.

Would be nice to have some suggested colours too for new custom factions, if you find some spare colours, also finding a colour palette with easily distinguishable colours would be nice, atleast some games run up to 12 colours somewhat differentiated.
