is there anyway i can change the color of my civilization. I always use the french and they are always blue is there anyway i can change this.

In the Assets/XML/Civilizations folder, you'll find the "Civ4CivilizationsInfo.xml" file... in it is the civ color, which can be changed/swapped here.

Of course, don't change your default XML file... copy it into a mod or custom assets folder before you change it.
