This is a very simple pack that requires Optifine or Colormatic. Note: Colormatic is not yet updated for 1.19.4 at this time, so for now, I would recommend using the mod called Old Potions which is available for both Fabric and Forge!

This pack really just uses this file, which already had the original colors!
