Colorblinding: Simulate Color Vision Deficiency

Free Chrome extension to test website accessibility for people with color blindness, useful for designers and developers

What is Colorblinding?

Colorblinding is a free Chrome extension that allows web designers, developers, and content creators to simulate different types of color vision deficiencies on web pages. This enables them to experience how their content appears for people with color blindness and ensure it is inclusive and accessible for people with vision impairments.

The extension provides real-time previews of web pages by applying color filters that mimic the most common types of color vision impairment such as red-green color blindness, blue color blindness, and full color blindness. Users can easily toggle between the different vision simulations and their normal vision.

Key features include:

• Simulate protanopia (red color blindness), deuteranopia (green color blindness), tritanopia (blue color blindness), achromatopsia (full color blindness), and other types of color vision deficiency.
• Adjust color simulation intensity from mild to strong.
• Quickly toggle between different vision simulations and normal viewing mode.
• Test on any web page to experience how people with color vision impairments will perceive colors and contrast.

By using Colorblinding to view their websites, apps, images, dashboards, data visualizations and other content through the lens of different color vision impairments, developers can identify problem areas such as low contrast text or reliance on color alone to convey meaning. They can then improve the accessibility and inclusiveness of their digital content.

The extension is completely free and easy to install for Chrome. It's an essential accessibility testing tool for any content creator who cares about inclusive design.
