What types of color blindness does this simulator support?

Our simulator supports all major types of color blindness including protanopia (red-blind), protanomaly (red-weak), deuteranopia (green-blind), deuteranomaly (green-weak), tritanopia (blue-blind), tritanomaly (blue-weak), achromatopsia (complete color blindness), and achromatomaly (partial color blindness). Each type uses scientifically accurate transformation matrices.

How accurate are the color blindness simulations?

The simulations use industry-standard color transformation matrices based on research from color science organizations. While no simulation can perfectly replicate individual experiences, these mathematical models provide highly accurate approximations of how different types of color vision deficiency affect image perception.

What image formats are supported?

We support common web image formats including PNG, JPEG, and GIF files up to 10MB in size. For best results, use high-quality images with good contrast and resolution. Images are processed locally in your browser for privacy.

Why is color blindness simulation important for accessibility?

Approximately 8% of men and 0.5% of women experience some form of color vision deficiency. Testing your images and designs ensures they remain effective and accessible for these users. This is crucial for web accessibility compliance (WCAG guidelines), inclusive design, and reaching diverse audiences.

Can I download the simulated images?

Yes! Each simulation can be downloaded individually as a PNG file. This allows you to share accessibility testing results with your team, include simulations in documentation, or use them for design validation purposes.

How does this differ from color contrast checkers?

While color contrast checkers measure the contrast ratio between two specific colors, color blindness simulators show how entire images, graphics, and designs appear to people with different types of color vision deficiency. This provides a more comprehensive view of visual accessibility.

Color Blindness Simulator

Simulate how images appear to people with different types of color blindness including protanopia, deuteranopia, tritanopia, and complete color blindness. Essential accessibility tool for designers, developers, and content creators to ensure inclusive visual content for the 8% of men and 0.5% of women affected by color vision deficiency.
