# PaletteLive > Free Manifest V3 browser extension to extract, edit, and export any live website's full color palette in real time. Website: https://palettelive.mckesav.in Install: https://microsoftedge.microsoft.com/addons/detail/palettelive/dglieojmcknbngkffpephfdphbdfbcam Author: MCKesav (https://www.linkedin.com/in/mckesav) Price: Free Browsers: Microsoft Edge, Chromium-based browsers ## What is PaletteLive? PaletteLive is a persistence-first palette system for real websites. It scans the full DOM (including Shadow DOM and CSS variables), overrides colors in real time with non-destructive inline CSS patching, enforces WCAG accessibility contrast standards, and persists changes per domain — across reloads, SPA route changes, and browser back/forward cache — without touching source code. ## Core Features (17 total) - Shadow DOM support — detects and overrides colors inside Web Components and Shadow roots - SPA route resilience — overrides persist through React Router, Next.js, and Vue Router route changes - BFCache resilience — re-applies overrides after bfcache restores - Per-domain persistence — changes synced across all tabs on the same domain - Real-time override persistence — edits saved instantly, no clicking Save - Undo / redo history — full edit history like a design app - Before / after comparison — split-screen overlay of original vs overrides - Color heatmap — overlays every colored element with its hex value - Click-to-edit color picker — click any element, pick a new color, instant apply - 6 harmony generators — complementary, triadic, split-complementary, and more, each scored for balance - Color clustering — groups similar colors to consolidate messy palettes - CSS variable detection — reads and rewrites :root and scoped CSS custom properties - Pseudo-state color detection — captures :hover, :focus, :active, :visited colors - Import & auto-map palettes — paste a Figma palette or design token file and auto-map - WCAG auto-fix — one-click contrast auto-fix to meet AA or AAA - Vision simulation — simulates 8 types of color vision deficiency - Multi-format export — JSON, CSS Variables, Tailwind Config, W3C Design Tokens, OKLCH, CIE LAB, CMYK ## Use Cases - UI/UX Designers: rapid brand exploration on live sites - Frontend Developers: inspect and refactor real-world color systems - Accessibility Auditors: test contrast compliance instantly - Design System Teams: extract and export structured tokens - Brand Designers: re-skin competitor layouts for pitch decks - QA Teams: validate dark mode and theme consistency ## FAQ Q: Does PaletteLive modify the website's source code? A: No. Overrides are applied at runtime via inline CSS patching. Changes live in the browser and can be persisted per domain without editing the site's codebase. Q: Will it slow down pages? A: PaletteLive scans efficiently and re-applies overrides only when needed. The watchdog/mutation observer stays sticky without constant heavy reprocessing. Q: Does it work with React, Vue, Next.js, and SPAs? A: Yes. Persistence across SPA route changes is a core feature. Overrides survive re-renders and route transitions. Q: Is it safe? Does data leave my browser? A: All processing is client-side. No tracking, no analytics on visited pages. Permissions are used solely for scanning and applying your own overrides. Q: Why not just use DevTools? A: DevTools doesn't give you a persistent per-domain override engine, palette clustering, harmony generation/scoring, WCAG auto-fix, or multi-format export workflow. Q: Can I export to Tailwind and design tokens? A: Yes. CSS variables, JSON tokens, Tailwind config, plus OKLCH/LAB/CMYK and export history. ## Pages - Home: https://palettelive.mckesav.in/ - Features: https://palettelive.mckesav.in/#features - Feature Comparison: https://palettelive.mckesav.in/#compare - FAQ: https://palettelive.mckesav.in/#faq - Privacy Policy: https://palettelive.mckesav.in/privacypolicy - Contact: https://palettelive.mckesav.in/#contact - Support: https://palettelive.mckesav.in/supportdev ## Contact Email: mckesavdev+support@gmail.com GitHub: https://github.com/MCKesav/PaletteLive LinkedIn: https://www.linkedin.com/in/mckesav
