Bad Ronald's Custom Colors and Flags v2.0 All Changes Pictured Below: In each subsection of the above picture: the large flag that appears to the right of the minimap within the game is at the top left, a small pic which shows the color of the civ's border is at the bottom left, a unit with the flag to its left is in the center, and the civ's color as depicted in the minimap is at the top right. I have created new flags for every civilization except Mali, Egypt, Inca, and Aztecs (suggestions are welcome). Most are simply the modern flags of the nations in question, but for some others I either took an earlier flag or fabricated one. Actual Flags from an Earlier Period The Russians use the Imperial flag not the modern one (I think it fits best with the Russian leaders). I did not give the Romans the modern Italian flag but SPQR has been added to the center of the laurels, and Germany has the red, white and black tricolor (both since it fits nicely with the leaders and looks better with the default German color - gray). Fabricated Flags Designed to Emulate the Pattern of Modern Ones For some civilizations, I designed a flag from the perspective of "if in the time this nation/leader existed, the modern format of flags was made use of, what might their flag look like?" With that in mind, I made the Chinese flag purple and gold with a purple dragon inside the gold section. The Persian flag is based on the modern flag of Iran with these exceptions: the colors were changed from red and green to cyan and orange (Persia's civ colors) and the central symbol is now a Zoroastrian Faravahar. The Mongols' flag is based on that of modern Mongolia with these exceptions: the colors are now brown and black (Mongolia's civ colors) and the stripes were changed from three equal sized vertical ones to the pattern you see above with the leftmost stripe twice the size of the two on the right (to better accomodate the symbol). Color Changes Rome now has a burgundy color, which I think is more fitting than the default purple. I replaced England's former white with crimson red (barbs are now white). Japan's red has been given a slight orange tint, and the Russians are now yellowish orange to match the color of the imperial flag. Spain is yellow (also matching the flag), and Egypt is black. India has been made a dark orange, and, finally, China is purple to match their flag. Testing Color Contrasts Since England and Japan are both red, I placed them on a map to ensure that they are distinguishable (contrast with England and Germany with the default colors). In Close: Zoomed Out: Installation (repeated in the readme): Either unzip the file directly to '%Documents Folder%\My Games\Sid Meier's Civilization 4\Custom Assets\' (there is a link to this folder in the Civ 4 root directory), Or cut and paste the 'art' and 'xml' folders into the Custom Assets directory after unzipping To Uninstall: (repeated in the readme) Navigate to your custom assets folder and: Delete the all of the .dds files in '\art\Interface\TeamColor\' Delete '\xml\art\CIV4ArtDefines_Civilization.xml' Delete '\xml\interface\CIV4ColorVals' and '...\Civ4PlayerColorInfos' Delete '\xml\civilizations\CIV4CivilizationInfos.xml' Expansion Pack Options Pictured Below: In the Instructions.txt file (included in the Expansion pack zip) you will find instructions on how to change any flag that you'd like to the modern flag of the nation in question (or the closest equivalent). I also included the Union Jack as an option for anyone who would prefer it. For the five nations absent (i.e., America, Arabia, France, Greece and India), the flags in the standard pack are already the modern flags; so, it is possible to have all nations represented with modern flags by combining the expansion pack with the default one. The Instructions.txt file explains how to replace as many or as few flags as you'd like, so it's not necessary to use the Italian flag to represent Rome if you don't want to, etc.
