Experience your designs through different eyes. Simulate Protanopia, Deuteranopia, and Tritanopia to ensure your images, charts, and UI are accessible to everyone. 100% private and secure.
👁️ Launch Simulator Tool → ⚡ Multi-Condition Simulation • 🔒 100% Private • 🚀 Instant ResultsSimulate Red-Blindness (Protanopia), Green-Blindness (Deuteranopia), and Blue-Blindness (Tritanopia) to identify potential color clashes in your UI.
Your creative assets stay on your machine. All simulation filters are applied locally in your browser, ensuring total privacy for sensitive mockups.
Upload an image and switch between different vision types instantly. See exactly where your design fails to provide enough contrast for color-blind users.
Our simulator uses scientifically accurate color transformation matrices to provide the most realistic simulation of color vision deficiencies.
Drag and drop or click to select the screenshot or design you want to test.
Switch between different color blindness types to see how the colors shift for different users.
Identify where information is lost due to color similarity and adjust your design for better accessibility.
Ensure that charts and graphs remain readable when the legend relies solely on color to differentiate data points.
Test if success/error states (Green/Red) are distinguishable for all users by adding icons or texture alongside color.
Verify that key calls-to-action (CTAs) and text overlays remain prominent and legible across different vision types.
We value your creative intellectual property. Our simulator runs purely in your browser's RAM; no images are logged, saved, or transmitted to any server.
We support Protanopia (red-blind), Protanomaly (red-weak), Deuteranopia (green-blind), Deuteranomaly (green-weak), Tritanopia (blue-blind), and Achromatopsia (total color blindness).
While this is an excellent visual aid for inclusive design, we recommend also using our Accessibility Checker to verify specific contrast ratios for text.
