ColorBlindness
by cech12
In ColorBlindness, potion effects imitate several forms of color vision deficiency, letting players experience how the game looks with reduced color perception.
What it does
The mod adds brewable potions that simulate color blindness. Each potion applies a visual effect that shifts how colors appear on screen, covering red, green and blue weakness as well as full achromatopsia. The Achromatopsia effect lasts 10 seconds when a player drinks it, and the others follow the same pattern of timed color shifts.
The purpose of the mod is to provide these color blindness effects as a shared library, so other mods can add their own potions and items that use them. Fabric API is required on every loader, and the same version is published for Fabric, Forge, NeoForge and Quilt. The mod is compatible with Optifine shaders, so the effects still apply when shaders are active.
Servers that run it need every player to install it too. The code is released under the MIT License and is open source, with a public source repository, issue tracker and wiki. Builds cover 1.16.5 – 26.3, and the latest file for 26.3 is dated 2026-09-20.
Key features
Brewable color blindness potions
Potions can be brewed to apply red, green and blue weakness and blindness effects to the player.
Achromatopsia effect
The Achromatopsia effect removes color from the view and lasts 10 seconds per potion.
Library hooks for other mods
Other mods can register their own potions and items that reuse these color blindness effects.
Shader compatibility
The visual effects remain visible with Optifine shaders active, so the simulation works in shaded scenes.

Use cases
Accessibility education
Players or teachers can drink a potion to see how a color vision deficiency changes the look of a build or a map.
Modpack additions
Pack authors can build new potions and items on top of the library and keep one shared color effect system.
Who it’s for: The mod suits players who want to test color perception in survival or creative worlds, and modpack authors who add brewable content that uses these effects. Players on a server need it installed, since the environment is client and server.
