Check your color contrast in real-time with a live preview right on the page before you commit to anything. 3. Get instant, accessible color alternatives when a combination fails so you can fix it without starting over. Color Contrast Checker by Accessibility Tracker is a free, professional-grade tool built for designers, developers, and accessibility professionals who need to verify color contrast ratios against the WCAG standard. Whether you are working toward WCAG 2.1 AA or WCAG 2.2 AA/AAA conformance, this extension gives you instant, accurate results without leaving the page you are testing. Color contrast is one of the most common accessibility failures on the web. Low contrast between text and its background makes content difficult or impossible to read for people with low vision, color vision deficiencies, or situational impairments like screen glare. Meeting the minimum contrast ratios defined in the WCAG standard is a fundamental part of making digital content accessible to everyone. This tool does more than check a ratio. It helps you fix contrast issues on the spot with smart color suggestions and gives you a real-time preview so you can see exactly how your changes will look before you commit to them. WCAG Success Criterion 1.4.3 (Contrast Minimum) requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text at the AA level. Success Criterion 1.4.6 (Contrast Enhanced) raises those thresholds to 7:1 and 4.5:1 at the AAA level. Non-text contrast under Success Criterion 1.4.11 requires a ratio of at least 3:1 for user interface components and graphical objects. These requirements exist under both WCAG 2.1 and WCAG 2.2. Failing to meet these ratios means your content is harder to perceive for a significant portion of your audience. What This Extension Does Instantly calculate the contrast ratio between any foreground and background color combination. Results are displayed as a pass or fail indicator for WCAG 2.1 AA, WCAG 2.2 AA, and WCAG 2.2 AAA levels. Pick colors directly from any webpage using the built-in eyedropper tool powered by Chrome's native EyeDropper API. No need to inspect elements or dig through stylesheets — just click on any element and the extension captures the exact color value. Get accessible color alternatives automatically. When a color combination fails, the extension uses the OKLCH color space to suggest the closest conformant alternatives so you can fix issues without starting over from scratch. Track and reuse previous color combinations with the built-in color history. This is especially useful when auditing multiple pages within the same site or working within an established design system. See changes before you make them with the live preview. Enter any foreground and background color combination and the extension renders a real-time sample so you can evaluate readability before updating your code or design file. Enter colors in whichever format you prefer. The extension supports HEX, RGB, HSL, OKLCH, LAB, LCH, and named colors. Convert between formats instantly. In addition to WCAG 2.1 and WCAG 2.2 conformance checking, the extension includes experimental support for the Advanced Perceptual Contrast Algorithm (APCA), which is the contrast method being developed as part of WCAG 3.0. APCA uses a more perceptually uniform model that accounts for how human vision actually processes lightness differences between text and background colors. This gives you a head start on future conformance requirements while still grounding your work in the current WCAG standard. Full dark mode support with automatic system preference detection. Export and import your settings and color history to back up your configuration or share it across devices. All data is stored locally on your device — the extension does not track you and does not send any data to external servers. Chrome 95 or later (required for the EyeDropper API).

This color contrast checker is a free tool from Accessibility Tracker, built to give accessibility professionals, designers, developers, and anyone who needs to verify color contrast a fast, reliable, and private way to check conformance directly in the browser.

WCAG Color contrast checker
To check the color contrast between foreground and background of the texts It checks the color contrast between the foreground and background of the elements that are in the page according to the WCAG 2.2. It evaluates the contrast on all elements of the page considering their computed style for the color and background-color CSS properties. In case of these colors are defined with RGBA values, it also considers the opacity to deduce the real color that finally is show. It can simulate color blindness and evaluate the contrast for the simulations. By this way, developers can see how the pages look for colorblind users. The tool also includes two fields in which the colors can be introduced manually to be tested. It also allows to pick the color directly from the documents. Finally, it auto-refreshes when DOM of the page changes (addition or removing elements), but if the page has many changes, this behavior can be de-activated.
