Simulate and correct color-blindness (CVD) locally with a single fast SVG filter. Private — no data leaves your device. See the web the way it really looks, or the way you need it to. Color-Blindness Simulator + Corrector applies a single fast SVG filter to any page so you can preview common color vision deficiencies or shift colors into a range you can tell apart. Everything runs right in your browser. WHAT IT DOES - Simulate protanopia, deuteranopia, tritanopia and related CVD types on any page - Correct on-page colors to boost contrast and separation for easier reading - Uses one lightweight SVG filter for fast, smooth rendering - Toggle on or off per tab whenever you need it - Remembers your preferred mode between sessions PRIVATE BY DESIGN No account. No sign-up. No tracking. All processing happens locally on your device, and no page content or personal data is ever sent anywhere. Permissions: - storage: saves your chosen simulation or correction mode so it persists across sessions - activeTab: applies the filter to the page you are currently viewing - scripting: injects the SVG filter into the page to transform its colors - alarms: schedules lightweight background timing tasks - notifications: shows occasional status messages when relevant Privacy policy: https://zovo.one/privacy-policy
