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.
