Colorblind-Tune — Colorblindness Accessibility Tool

Colorblind-Tune provides a built-in color vision screening and adaptive filter algorithm for a better browsing experience.

ColorBlindify is a modern visual accessibility extension designed to help users with color vision deficiency. It combines a data-backed digital test suite with intelligent, adaptive color correction to deliver a fast, usable experience directly in Chrome. ONCE DOWNLOADED: Click the extension icon, pin it and click on it → take the color vision test (2-3 minutes) or go straight with the filters. 🔍 What it does 38 standardized pseudo-Ishihara plates for quick screening. Real-time answer tracking and response analysis in the browser. Instant personalized recommendation based on performance. Adaptive filter mode selection (simulate/correct) and severity setting. 🧠 Algorithm and accuracy story Uses a trained scoring engine that maps response patterns to a color vision severity index. Computes a normalized intensity score (0.0–1.0) that translates to: 0 = normal (no filter) 0.3 = mild 0.6 = moderate 1.0 = strong The algorithm integrates both exact and near-miss responses to reduce false positives and create a resilient defect-score estimate. Results are shown in a clear “severity + recommendation” format, helping users choose practical filter strength quickly. 🆘 Accessibility-first design Clear UI with large controls and high contrast. Keyboard-friendly quiz interactions. Built-in reset & adaptive intensity feedback so people with different vision profiles can tune differently. 🛡️ Privacy + policy-safe No personal identity collection. Only local Chrome sync storage for user filter preferences. No server-side data unless user opts for submission in future versions.
