Tritanopia Color Blindness Shaders
Tritanopia Color Blindness Shaders (1.21.1, 1.20.1) simulates the color blindness. It is an Optifine shader, not a resourcepack shader. Color blindness is when you don’t see colors in the traditional way because some cones (nerve cells) in your eyes are missing or don’t work correctly. You may have trouble seeing the difference between certain colors or shades, or perceiving the brightness of colors.
