Colorblind Filter

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

🎨 Work with visual perception directly in your browser colorblind filter changes how the current site is rendered. It is built for users with color vision deficiency and for designers, developers, and QA teams testing interfaces. 🚀 Two modes in one extension 1️⃣ For me — apply correction settings that can make some differences easier to distinguish. 2️⃣ Test website — use a color blind simulator to preview how a page may look with different vision types. 3️⃣ Switch modes instantly without reloading the page. Processing works locally in Chrome, with no external backend. 👁️ Correction for everyday browsing Use correction mode when certain shades or combinations are difficult to tell apart. ➤ protan colorblind filter for red-related perception adjustments. ➤ deutan adjustment for common red-green perception differences. ➤ blue yellow colorblind filter behavior for tritan-related cases. Change intensity with a slider and use Hold to compare to temporarily restore the original appearance. Save for this site stores the selected mode, preset, and intensity for the current domain. 🧪 Simulate different vision types The simulator includes eight presets: - Protanomaly - Protanopia - Deuteranomaly - Deuteranopia - Tritanomaly - Tritanopia - Achromatomaly - Achromatopsia For design reviews, a color blind simulator helps teams inspect UI states, charts, alerts, buttons, and other elements without switching tools. 🔴 Red-green and blue-yellow checks A red green colorblind filter helps explore a common problem area in interface design. The red green color blindness filter workflow is useful when status indicators, validation states, or charts rely too heavily on hue. • Use red/green colorblind filter presets to inspect red and green combinations. • Use deuteranopia filter simulation for one specific type of deficiency. • Use tritan presets when blue and yellow differences matter. This makes the colorblindness filter useful for focused visual QA. 🖼️ Images, video, and dynamic pages The extension can include images and video in processing, so colorblind filter for images is useful when media matters as much as interface elements. 1. Enable Include images & video. 2. Adjust intensity until the effect is easy to evaluate. 3. Use Hold to compare before and after states. The colorblind image filter works with SPA navigation and applies changes without a manual reload. An image colorblind filter workflow also helps inspect banners, illustrations, thumbnails, and embedded media. ⚙️ Built for repeat use colorblind filter chrome settings can be remembered between sessions. ▸ Save the last selected mode. ▸ Save settings for a specific site and apply them automatically next time. ▸ Keep processing local without sending page data outside the browser. Use saved website settings when one domain needs a consistent configuration across visits. 📊 Check color vision with Ishihara The extension also includes an ishihara color test for a quick screening of perception. It is separate from simulation and correction modes. 📌 What does the Ishihara test do? 💡 It presents color plates commonly used to screen for red-green vision differences. It is a screening aid, not a medical diagnosis. 📌 Can it replace a professional examination? 💡 No. If you need a clinical assessment, consult a qualified eye-care professional. The test adds a practical check colorblind workflow and can complement a separate daltonism test online. 🔍 Useful for different scenarios For users, color blind filter controls can make some page elements easier to distinguish. For product teams, color blind checker and colorblind checker workflows help reveal where an interface depends too much on hue alone. For QA, daltonism simulator presets make it easier to inspect several color vision conditions during visual testing. This supports color blindness vision checks different presets. daltonism color blindness covers correction, simulation, and screening scenarios. 🛠️ Focused tool for visual accessibility This is not a general accessibility suite. It is a focused colorblind web page filter for perception, simulation, and correction. Use the test workflow to compare modes and inspect UI states. For media, colorblind filter image processing extends the same behavior to images and video. Whether you need a color blindness filter for personal browsing or a colorblind simulator for product testing, the extension keeps the workflow simple and local.
