How to Change Which Colors Random Sheep Can Spawn With
Newly spawned sheep pull their fleece color from a list defined in the mod's configuration file. If you want to restrict sheep to a themed palette, or add back colors you previously removed, you edit that list rather than anything in-game.
Finding and Editing the Config
1. Locate the mod's config file in your Minecraft config folder. It is a plain text file, so any text editor works.
2. Open it and find the entry that holds the list of allowed wool colors. Each color is listed as a separate value.
3. Remove any color you do not want sheep to spawn with, or add colors you want included. Keep the formatting of the existing entries intact — the mod reads them literally.
4. Save the file.
Applying Your Changes
Reload the config by restarting the game or world. The list is read when sheep spawn, so already-existing sheep keep the color they were born with; only newly spawned sheep use the updated list. If a color you added does not appear, double-check its spelling against the other entries, since an unrecognized value is simply skipped. To test quickly, spawn several sheep in a creative world and watch the colors that come out.
