ColorLight

Installed on the client, the mod reads a block's texture, finds its dominant color and uses that color as the light the block emits. Players can adjust the glow radius and enable light smoothing, and the mod's light propagation method determines how the colored light spreads. Shaders built for ColorLight need support from their own authors, and some mods that add features beyond vanilla light handling may require a separate ColorLight integration.

Lighting can also be set through commands, so builders on maps, structures and vanilla servers can place their own light sources. The mod adds its own light block, which works natively with the colored lighting, and the author notes that sharing light sources with other players, across servers, local worlds and save files, is planned. Settings are split into tabs, with the General tab and the Blocks tab handling different parts, and the mod's settings live in Sodium's menu. Optimization mods are supported.

ColorLight requires Fabric API and runs on Fabric for 26.3 and earlier builds listed here, covering 1.21.1 – 26.3. It is client-side only, so the server does not need it, and it is released under the MIT License as open source, with public source code and an issue tracker. Sodium is an optional dependency.
