I never thought about this until I just joined two games, in each game I am Yellow and in each game I'm surrounded by the same colors, purple, dark blue, light blue, and olive. And in one game I send a chat message "well maybe you shouldn't have attacked my outpost first." And the other guy was like "what, I didn't?" And turns out it was the other light blue in the other game I'm playing that had attacked my outpost in that game that I was thinking of which now got me on bad terms with the other light blue in my second game. Very confusing! I agree different colors and randomized colors (not assigning a color based on join order) would be a great addition.
