Protanopia Color Blindness Shaders
Protanopia Color Blindness Shaders (1.20.4, 1.19.4) simulates the color blindness. It is an Optifine shader, not a resourcepack shader. Color blindness (color vision deficiency) is a fairly common condition in which you donât see colors in the traditional way. This happens when cones (a type of nerve cell in your eye retina) arenât working correctly. Cones process light and images as they enter your eye and send signals to your brain that allow you to perceive color.
