What is RGBlind.com?

RGBlind.com is a comprehensive, browser-based platform for simulating and testing color vision deficiencies. It allows designers, developers, educators, and parents to see how images, websites, and digital content appear to people with various types of color blindness, including protanopia, deuteranopia, tritanopia, and achromatopsia.

The platform includes a Color Blindness Simulator that supports multiple input options—uploading images, pasting URLs, or using a real-time camera feed. Users can adjust severity, enable daltonization (color correction), and use tools like split-view comparison, grid overlays, and zoom loupe for detailed inspection.

RGBlind.com also offers the Ishihara Color Vision Test for Adults, a 32-plate online screening tool designed for educational and awareness purposes, and a Kids Color Blind Test, a shape-based test suitable for children aged 4–12, helping parents and educators identify potential color vision issues early.

The platform runs entirely in the browser, requires no installation, and processes everything locally for privacy. RGBlind.com is fast, mobile-friendly, and helps creators ensure accessibility compliance with standards like WCAG, ADA, and Section 508. It is ideal for anyone looking to create inclusive digital experiences or learn more about color vision differences.
