Batch Workflow
Audit whole image assets or UI kits in seconds. Upload hundreds of files and download the simulated results as a single ZIP archive.
How to Simulate Color Blindness in 3 Steps
Upload Your Assets
Drag and drop your design mockups or photos. We support high-resolution PNG, JPG, and WebP files.
Select Deficiency Type
Choose between Protanopia, Deuteranopia, Tritanopia, and others. Adjust the intensity to simulate partial color blindness.
Batch Download
Export the simulated images in your preferred format. Download them all as a ZIP for your accessibility report.
Frequently Asked Questions
What types of color blindness can be simulated?
We support simulation for Protanopia (red-blind), Deuteranopia (green-blind), Tritanopia (blue-blind), Achromatopsia (total color blind), and their anomalous counterparts (partial deficiency).
How accurate is the simulation?
Our simulator uses industry-standard color transformation matrices derived from scientific models (Machado et al.) to provide highly realistic previews of color vision deficiencies.
Can I use this for high-resolution images?
Yes. Since all processing is done locally using your browser's hardware acceleration, you can process large, high-resolution images quickly without waiting for server uploads.
