Radiant Spectrum Logic Mod generates colored lighting based on the textures of glowing blocks in your world. The mod scans the texture of any light source, finds the dominant color, and casts that exact shade onto surrounding surfaces. It works directly alongside shader packs and optimization mods without requiring special shader patches. Builders and server owners can also place custom light sources across maps using in-game commands.
