Smooth Saturation
Smooth Saturation is a resource pack that doubles color saturation in your game while maintaining full compatibility with other resource packs.
IMPORTANT NOTICE! Starting from version 1.21.2, some elements have stopped rendering correctly, including hand-held items, experience orbs, various particles, and possibly other objects I haven't noticed yet. If you understand vanilla shaders and know how to fix these issues, please contact me through my Discord group.
