A free mod for Mount & Blade II: Bannerlord, by DW420.
Tiny BannerPaste Palette is a mod that lets you change the look of the banners that appear when you enter a new area. It lets you choose from several different palettes, and it’s very easy to install.
The main focus of this mod is to change the look of the banners in the game. However, it is not just a simple colour change as it lets you choose from several different shades. It is a very simple and easy mod to install, but it will possibly conflict with other mods that alter the same fame files.
