Shaders
by Frqme
Shaders gives players animated rainbow and gradient outline effects on entities and held items, configurable from the client options.
What it does
The mod is a Fabric client mod that draws customizable, animated outline colors around entities and held items. Rainbow cycles and gradient transitions can be set up in the options, and the visual styles can be tuned to the player's taste. Outline styles change only how things look, with no effect on gameplay.
Because the mod only alters rendering on the player's own client, it runs without any server-side install and has no bearing on mechanics. It is not a tool for revealing hidden entities or changing world behavior. Files target 1.21.11 only, and the latest Fabric build is 2.2, published on 2026-06-22. Shaders is released under All rights reserved and is not open source.

Use cases
Colorful screenshots

Visual personalization
Players who want a different look for their own client can set up rainbow and gradient outlines without touching gameplay.
Who it’s for: Players who want to customize how entities and held items look on their own screen. The mod suits single-player and multiplayer clients alike, since only the player's own display changes.
