About This Color Blindness Simulator

This browser-based color blindness simulator shows how colors appear to people with different types of color vision deficiency. Essential for designers and developers testing color accessibility. Simulate protanopia (red-blind), deuteranopia (green-blind), tritanopia (blue-blind), and achromatopsia (total color blindness). All simulations run in your browser with complete privacy.

Supported Color Vision Deficiencies:

Protanopia: Red color blindness - difficulty distinguishing red from green
Deuteranopia: Green color blindness - most common form of color blindness
Tritanopia: Blue color blindness - rare blue-yellow color confusion
Achromatopsia: Total color blindness - see only in grayscale
Real-time Simulation: Instant color transformation as you select colors

Use Cases:

Test website and app color accessibility
Design inclusive color schemes
Verify color contrast for readability
Understand color perception differences
Meet WCAG accessibility guidelines

🔒 Privacy-Friendly: Color simulations happen entirely in your browser. No data is sent to any server.
