Colorblind Filter

Test websites with colorblind filter, use color blind simulator, check colorblind vision, and explore daltonism simulator modes

🎨 Meet Colorblind Filter — a Chrome extension for comfortable browsing and visual accessibility testing. Adjust website colors for your own vision or explore how a page may look to people with different types of color vision deficiency. Everything works directly on the current page, so you can compare colors without changing your workflow. 🚀 Quick start 1️⃣ Install the extension from the Chrome Web Store. 2️⃣ Open any website you want to adjust or inspect. 3️⃣ Choose “For my eyes” to improve color distinction for yourself. 4️⃣ Choose “Through their eyes” to use a color blind simulator for design and QA checks. 5️⃣ Adjust intensity and compare with the original. 👁️ Make website colors easier to distinguish Some interfaces rely heavily on red, green, blue, or yellow differences. This can make buttons, charts, alerts, and labels harder to recognize. Colorblind Filter lets you apply correction presets and adjust their strength with a slider. ➤ Try a red green colorblind filter when red and green elements are difficult to separate. ➤ Use protan-related correction for red perception differences. ➤ Explore blue-yellow adjustments when those combinations cause problems. ➤ Hold the comparison control to restore the original page temporarily. Save your preferred setup for a website and reuse it when you return. 🧪 See the interface from another perspective Designers, developers, and QA specialists can use the built-in colorblind simulator to inspect websites directly in Chrome. ◆ Check whether success and error states are distinguishable. ◆ Review charts, badges, and status indicators. ◆ Inspect links, buttons, forms, and navigation. ◆ Find places where meaning depends only on color. Use presets for common red-green, blue-yellow, and monochromatic vision variations. A deuteranopia filter, for example, can reveal interface states that become too similar under one simulation. 🖼️ Test images, video, and dynamic content Banners, illustrations, charts, and video may also rely on color. Enable media processing when you want a colorblind filter for images. 1. Turn on image and video processing. 2. Select correction or simulation mode. 3. Adjust the intensity. 4. Compare the result with the original. The extension supports dynamic pages and SPA navigation as content changes without a full reload. ⚙️ Built for repeated use ▸ Remember the last selected mode. ▸ Save settings for an individual website. ▸ Apply saved preferences automatically. ▸ Change intensity without reloading. ▸ Include images and video when needed. Use it as a personal color blind filter or as a testing tool for product teams. 📊 Calibrate your eyes Not sure which correction works best for you? Use Calibrate your eyes — a short Ishihara color test built into the extension. The test can help you notice possible red-green perception differences and choose a preset to try. 📌 Is this a medical diagnosis? 💡 No. The built-in test is a screening aid for choosing settings. It does not replace an examination by a qualified eye-care professional. 📌 Can I use it instead of a daltonism test online? 💡 You can use it as a quick color vision check, but it is not a clinical assessment. 🎯 Who can benefit? • People who want website colors to be easier to distinguish. • Designers checking interfaces before release. • Developers reviewing UI states in the browser. • QA specialists looking for color-dependent usability issues. 💡 Useful scenarios - Check a flow where errors are shown only in red. - Review charts with similar colors for different data series. - Test a design with a color blindness filter before release. - Use a color blind checker while reviewing an existing product. - Compare a live page with a daltonism simulator directly in Chrome. ❓ Frequently Asked Questions 📌 What does the extension do? 💡 It combines color correction with color vision simulation. Adapt websites for your own browsing or test how interfaces may appear under different presets. 📌 Can designers use it for accessibility testing? 💡 Yes. Use the color blind simulator to review UI states, charts, alerts, forms, and other elements on a live website. 📌 Does it work with images? 💡 Yes. Enable image and video processing to inspect media together with the rest of the page. 🌈 Browse more comfortably. Test more thoughtfully. See color from a different perspective.
