What Does Prism Mod Do?
A Color Library, Not a Content Mod
Prism Mod is a library mod, meaning it does not add its own blocks, items, or mobs. Instead, it extends color functionality for other mods that depend on it.
The clearest example is Minecraft's built-in TextColor system. Normally, text colors are static. With Prism Mod installed, any dependent mod that uses TextColor automatically gains support for animated colors, web colors, and easy HSV manipulation — without that mod needing to implement these features itself.
Because of this, Prism Mod on its own will not visibly change your game. You will only notice its effects when you also have a mod installed that uses it. If a mod lists Prism as a dependency, that mod is using the library to handle its colors.
If you are searching for a Prism Mod menu or a Prism module for a specific game, note that this is a Minecraft library mod and does not provide an in-game menu or modules.
