Ishihara

About

This mod was created to help developers of mods and modpacks simulate colorblind types in the game. Allowing for an easy way to see if UIs, graphics, or anything may need adjusted to support impaired users. 

How to use

By default keybinds are set to “Ctrl+N”

Activating the keybind which will bring up a menu to select the colorblind type to enable. Once enabled a post processing shader will run to change everything rendered in the game to something as close as we can simulate to colorblindness. 

FAQ

Q: Will this work with optifine or other shader programs?

A: Unlikely but it should be easy enough for you to test. Install both mods and try to use them.
