Check Color Contrast

To assess the color contrast between the text's foreground and background.

Check Color Contrast is a lightweight Chrome extension built for designers, developers, and anyone who values inclusive digital experiences. It helps you assess the contrast between foreground text and background colors using the latest WCAG 2.2 guidelines — ensuring your content is readable, accessible, and compliant. With a single click, the extension analyzes the color pairing of any text element on the page. It calculates contrast ratios and instantly tells you whether the combination meets AA or AAA standards for normal and large text. Whether you're working on a website, app, or document, it’s a fast and reliable way to validate your design choices. The interface is clean and symbolic, using abstract shapes and minimal text to communicate contrast evaluation. A magnifying glass, checkmark, and color blocks form the core visual metaphor — making it feel native to Chrome while clearly signaling its purpose. It’s designed to be intuitive for both technical and non-technical users. Performance is fast and unobtrusive. The extension runs entirely on the client side, with no data tracking or external requests. It doesn’t interfere with your workflow or modify page content — it simply overlays contrast information when you need it. You can toggle it on and off from the toolbar, and results appear instantly. Whether you're auditing a full site or checking a single button, Check Color Contrast helps you catch accessibility issues before they reach your users. It’s a small tool with a big impact — empowering you to design with clarity, empathy, and confidence.
