I changed the colours of civs. I tried to give to every the colour of its flag of its golden activation period. For example Portugal is white and blue, because colonial portoguese colors where white and blue. I hope you like it.
Comments are welcome.
The colours were edited in improved graphics mod. Note that color perception is slightly subjective, so if you see a color different than what I say in the list, tell me to fix it.
Unfortunately, the mod is incompatible. Incombatibilities belong to the past! The new update is removable and won't affect anything!
