In case Stonehearth is not offering a feature like this already, I would really love to see this one…
The core of this mod would be some kind of a collecting game. Different colors would be “hidden” in the world. Once they are discovered, they will be added to the players “color map”. This color map would be created with an open and well documented interface / back-end, allowing other mods to access it.
The result would be some entertainment in the game by itself. But second (and not less important) it would allow other mods to access a color map and decide based on that, which customization-colors/-options should be made available to the player. More discovered colors would mean more customization options. If the game has a simple dyeing system in place, this mod should offer an option to other mods which one to chose.
New colors could be enabled by defeating monsters, killing creatures, finding treasures, harvesting fruits and vegetables, etc.
Maybe someone volunteers for that one .
