Remember to have a copy of Grand Theft Auto - San Andreas with CLEO 4 Installed.
Step 1 - Download the Extended Gang Wars mod by Silent and put the files you downloaded into your GTA SA directory
Step 2 - After installing the mod into your directory double click the ExGangWars configuration settings
Step 3 - Once you opened the text file you should see where It says "TurfColour=" and some Hex codes
Step 4 - Now you would want to go here
The website should be simple enough for you to be able to use.
Step 5 - After you'd obtained the color from the website that you wanted there should be a Hex code attached to that color
Like for the dark blue color It's #000055
Step 6 - After you got the Hex code now you would want to look back at your ExGangWars configuration settings and where It says "TurfColour=" then delete the Hex codes
Step 7 - Once you've deleted the hex codes you would want to paste the hex code of the color you got from the website and at the beginning of the hex code you added you would want to also add "0x". Remember to delete the hashtag from the hex code to If you forgot.
It should look like this
This doesn't change the color of the attack blip.
