Webcam Color Blind Simulator
Start your camera and instantly preview how the physical environment, printed materials, or on-screen UI looks to users with various types of color blindness. Supports 7 simulation types. All processing happens locally in your browser — no video is transmitted to any server.
Why This Matters
Color blindness affects approximately 8% of men and 0.5% of women. Testing your designs with a live camera lets you evaluate real-world materials (print, signage, presentations) that static image uploads cannot capture.

Frequently Asked Questions
Is my camera footage sent to your servers?
No. All processing happens entirely in your browser using the Canvas API. No video data ever leaves your device.
Which browser permissions are required?
The tool requires camera permission in your browser. Click "Allow" when prompted. You can revoke permission at any time through your browser settings.
What is the difference between Protanopia and Deuteranopia?
Both are types of red-green color blindness. Protanopia (red-blind) makes reds appear very dark. Deuteranopia (green-blind) makes greens appear indistinguishable from reds. Deuteranopia is the most common form, affecting ~6% of males.
