Description
Scan the current tab for color-blind accessibility issues. Pro feature of ColorCheck. ColorCheck scans the visible tab and the live DOM to find color combinations that fail for the 350+ million people with color vision deficiency (CVD). Works on production sites, staging, and localhost. What you get • Accessibility score — a single 0–100 number summarizing how well your colors hold up under CVD • Palette analysis — top dominant colors extracted from a screenshot, checked pairwise under protanopia, deuteranopia, and tritanopia • Flagged elements — a list of specific DOM elements (with selectors) whose text fails WCAG contrast or breaks under color-blindness simulation • Severity grading — high / medium / low so you can fix what matters first Built for designers + developers • One click — no setup, no DevTools panel • Works on any URL, including localhost and staging environments • Uses scientifically-validated Brettel CVD simulation matrices and WCAG 2.1 contrast formulas • Companion to colorcheck.dev — get full multi-page reports, AI palette fixes, and PDF exports on the web app Privacy first Nothing leaves your machine.
