How to Use

What types of color blindness are simulated?

The tool simulates protanopia (red-blind), deuteranopia (green-blind), tritanopia (blue-blind), and achromatopsia (total color blindness).

Why is this important for design?

About 8% of men and 0.5% of women have some form of color vision deficiency. Testing ensures your designs are accessible.

Can I use this for web design testing?

Yes. Upload screenshots of your website or UI designs to check how they appear to color-blind users.
