Colorblind Camera Filter
Free camera filter with two modes: Simulate shows designers how colorblind people see the world, Daltonize shifts colors so colorblind users can distinguish them better. Real-time processing of protanopia, deuteranopia, tritanopia, and achromatopsia — 100% in-browser.
Check accessibility or enhance colors for colorblind vision in real time

How to Use the Colorblind Camera Filter
Click "Start Camera" and allow browser access to your webcam or phone camera.
Select "Simulate" to see how colorblind people see, or "Enhance (Daltonize)" to make colors more distinguishable for colorblind vision.
Pick the type of color vision deficiency: protanopia, deuteranopia, tritanopia, or achromatopsia.
Use the severity slider (0–100%) to control intensity. Toggle fullscreen for immersive use. Compare with side-by-side view.
Frequently Asked Questions
Who is this tool for?
Two audiences: (1) designers and developers who need to check their work for color accessibility — Simulate mode shows how colorblind users see your designs. (2) People with color blindness who want to distinguish colors better — Daltonize mode shifts colors for better visibility.
What types of color blindness are supported?
Protanopia (red-blind, 1% of males), deuteranopia (green-blind, 6% of males), tritanopia (blue-blind, rare), and achromatopsia (total color blindness, very rare). The severity slider lets you test partial deficiency too.
Can colorblind people use Daltonize mode as "color blind glasses"?
Daltonize algorithmically shifts colors that are indistinguishable to colorblind users into ranges they can perceive. It works in real time via your camera — point it at signs, maps, charts, or anything with color-coded information.
Is my camera feed uploaded to any server?
No. All processing happens 100% in your browser using Canvas API. No video frames leave your device — your privacy is fully protected.
How accurate is the simulation?
The simulation uses the Machado-Oliveira-Fernandes model — the most accurate CVD simulation algorithm available in scientific literature. It is widely used in accessibility research.
Can I use this on my phone?
Yes. On mobile devices the tool uses your rear camera by default. Switch Camera button toggles between front and back cameras. Fullscreen mode works great on phones.
