Color Cone is a real-time color vision simulation shader designed to accurately reproduce how different types of color perception and color blindness affect visual output.

👁️ Supported Vision Modes

The shader includes simulation for:

Normal Vision
Deuteranopia (No Green Cone)
Protanopia (No Red Cone)
Tritanopia (No Blue Cone)
Deuteranomaly (Weak Green Cone)
Protanomaly (Weak Red Cone)
Tritanomaly (Weak Blue Cone)
Achromatopsia (No Cone Cells)
Blue Cone Monochromacy

Each mode transforms the rendered image to reflect the perceptual characteristics of the selected vision type.
