What this mod does is replace the blue backdrop with a red one, in all the menus in W:A. In addition, it changes the tooltip text color at the bottom of the screen, from teal to yellow, again in all the menus. I made this mod for myself but decided to share it since I saw no such mods for W:A anywhere on the web. I don't plan on updating it, but it should work fine, if you have no other mods changing the color palettes. Happy worming!
Just extract this in .../Worms Armageddon/graphics/ Tested in W:A v3.6.31, but should work in any version If you want to use it in your mod you don't have to ask my permission, but please give credit.
