Vibrancy (development paused)
Vibrancy gives Minecraft-style colored light shadows to blocks under the sky and to entities, a client-side visual change for Fabric and NeoForge.
What it does
Blocks that receive sunlight cast colored shadows in the style of the game's own light rendering, and entities cast shadows too. Because the change lives on the client, a single-player world or a joined server needs nothing extra on the server side and players alone decide whether to run it.
Vibrancy depends on Big Shot Lib on both loaders. On NeoForge the config layer is Yet Another Config Lib 4.1.0 or newer, while Fabric builds use Cloth Config 3.0.10 or 4.0.8 and Fzzy Config 3.0.9 or older. Sodium must be 0.8.0 or later on the newer versions, and 0.6.13 is the matching build for 1.21.1. Files cover 1.21 – 1.21.11, and the mod is released under the MIT License and is open source.
The author notes that the mod can technically run next to shader packs, but combining it with them is not planned. Development has been paused, and the source code and issue tracker are public. The mod is also compatible with the Sable mod.
Key features
Colored sky shadows

Config library support

Shader packs not planned
The author lists combining the shadows with shader packs as possible but not pursued.
