Onylogy Color Picker by Ehasanul Haque — eyedropper, palette extraction, accessibility checks, and developer exports. 🎯 Pick any color · 🎨 Extract any palette · ♿ Check WCAG contrast Onylogy Color Picker is the fastest, cleanest free color tool for Chrome, Vivaldi, Brave, Edge, and Arc. It turns any website into a complete color reference for your design or development workflow — with a pixel-accurate eyedropper, one-click palette extraction, a live element inspector, a WCAG 2.1 contrast checker, and one-click exports to CSS Variables, Tailwind config, SCSS, JSON, and Kadence Global Palette. No accounts. No tracking. No paid tier. Just the tool. ━━━━━━━━━━━━━━━━━━━━━━ WHAT YOU GET ━━━━━━━━━━━━━━━━━━━━━━ 🎯 PIXEL-PERFECT EYEDROPPER WITH ZOOM LENS Press the toolbar icon or hit Alt+Shift+P from anywhere. A circular zoom lens follows your cursor with crisp, blocky pixels so you can target individual pixels precisely. Choose between 1×1, 3×3, 5×5, or 9×9 averaged sample modes — perfect for grabbing the exact color of logos and gradients without snagging a stray pixel. Click to capture; the color auto-copies to your clipboard with a clean confirmation toast at the bottom of the page. 🎨 FULL-PAGE PALETTE EXTRACTION One click extracts a website's complete color palette. We walk the visible DOM, weigh each color by rendered area, and cluster perceptually similar colors in OKLCH space — the same color science modern design systems use. You get back 6–12 colors per page, each labelled with a semantic role hint: likely primary, secondary, accent, or neutral. 🔍 LIVE ELEMENT INSPECTOR Hover any element on the page and see its background, text, border (all four sides), shadow, gradient, opacity, and CSS custom property values in a clean floating tooltip. We composite alpha through parent layers so you see the actual visible color, not the misleading rgba(0,0,0,0) of a transparent overlay. ♿ WCAG 2.1 CONTRAST CHECKER Extract a palette and get a complete accessibility audit of every real text/background pair on the page, with AA and AAA badges at both normal and large text sizes. Background gradients and images are honestly flagged as "indeterminate" — no guessing. 📤 DEVELOPER-FIRST EXPORTS One click copies your palette in the format you actually use: ✓ CSS Variables with @supports oklch() fallback ✓ Tailwind config (theme.extend.colors) ✓ SCSS variables ✓ JSON (full hex / rgb / hsl / oklch) ✓ Kadence Global Palette (experimental) ⌨️ KEYBOARD-FIRST WORKFLOW ✓ Alt+Shift+P — open the sampler from anywhere ✓ 1 / 2 / 3 / 4 — switch between Picker, Palette, A11y, Export tabs ✓ C — copy the current color ✓ Esc — exit 🎨 EVERY MODERN COLOR FORMAT HEX · RGB / RGBA · HSL / HSLA · OKLCH ━━━━━━━━━━━━━━━━━━━━━━ PERFECT FOR ━━━━━━━━━━━━━━━━━━━━━━ ✓ WORDPRESS DESIGNERS Extract a client's existing palette in seconds; export directly to the Kadence Global Palette format. ✓ TAILWIND DEVELOPERS Land a polished tailwind.config.ts color object in one click, with OKLCH-grade perceptual accuracy. ✓ FRONTEND ENGINEERS Inspect computed styles 10× faster than DevTools, with effective background colors composited through transparent layers. ✓ UI / UX DESIGNERS Capture inspiration as you browse. Build moodboards from real production sites. Audit contrast before handing off mockups. ✓ ACCESSIBILITY AUDITORS Run a real-world WCAG 2.1 contrast audit of every text/background pair on a page, instantly. ━━━━━━━━━━━━━━━━━━━━━━ PRIVACY-FIRST BY DESIGN ━━━━━━━━━━━━━━━━━━━━━━ Zero network requests. No accounts, no telemetry, no analytics, no remote configuration, no version checks. Everything runs locally in your browser. Your recent colors are saved only in your browser's local storage and never transmitted. Minimum permissions only: ✓ activeTab — only acts on the tab you click on ✓ scripting — auto-injects so you don't have to refresh tabs that were open before installing ✓ storage — saves your recent colors locally We do NOT request <all_urls> host permissions, never read your tab list, and never touch your cookies or browsing history. ━━━━━━━━━━━━━━━━━━━━━━ OPEN SOURCE ━━━━━━━━━━━━━━━━━━━━━━ 100% open source under the MIT license.
