Chroma
by NitronRbn
Chroma is a Fabric library for rendering effects, providing particles, camera shake, lens flares and post effects for mods built on top of it.
What it does
Chroma collects rendering code that its author has used across several rendering-focused mods. Mod developers can call it for additive particles, camera shake driven by a Vec3 source, experimental lens flares and experimental post effects that can be added or removed at runtime. Its helpers also cover shaders, including the core ones, and render-layer utilities, along with GUI utilities for custom draw calls.
Chroma is a library, so it adds no items or blocks on its own and matters only to the mods that depend on it. The files are published for Fabric and target 1.21.11, with 1.2 as the latest build since 2026-07-05. The mod is released under All rights reserved, so it is not open source, and it is client-side only, meaning only the client needs it. Public links to the source code and a wiki are available.
Key features
Chroma particles
Additive particles that are simple to create, for effects that brighten where they overlap.
Camera shake
Shakes the camera from a Vec3 source position, so a shake can be tied to a point in the world.
Experimental lens flares
Lens flares can be attached to certain positions in the world, with the feature still marked experimental.
Runtime post effects
Post effects can be added and removed while the game runs, marked experimental by the author.

Use cases
Rendering-heavy mods
Developers building visual mods can reuse the particle, shader and draw-call helpers instead of writing them from scratch.
Who it’s for: Mod developers who build rendering-focused mods for Fabric 1.21.11 and want shared particle, shader and post-effect helpers. Players do not need to configure it directly.
