FAQ
The tool applies mathematical color transformation matrices to the pixels of your image to mimic how people with different types of color blindness perceive the world.
Your images are completely private. All processing happens client-side in your browser — no data is ever sent to any server.
You can simulate deuteranopia (green-blindness), protanopia (red-blindness), and tritanopia (blue-blindness).
Absolutely! This is a great way to verify that your graphics, websites, or marketing materials are accessible to people with color blindness.
