Clan Colours Mod
Changes the unit armour colours away from bright, synthetic dye looking colours to a more period accurate palette. Colours are generally darker and avoid intense artificial dye colours.
This mod should be compatible with pretty much any mod except for other colour mods (even then it won’t crash, just won’t display changed colours).
This is a very simple mod, anyone can edit it themselves with the Pack File Manager tool.
