DigitalA11Y Color Contrast Checker review
A focused free tool for checking color contrast, not broader accessibility coverage.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
DigitalA11Y Color Contrast Checker is a free Chrome extension for designers, developers, accessibility professionals, and others reviewing web color combinations. It supports one-click selection of foreground and background colors from webpages, along with manual hexadecimal color input. The extension calculates contrast ratios, displays WCAG compliance status, and suggests alternative color codes with stronger contrast. Its page-level scope makes it suitable for checking individual color combinations during website design, development, and accessibility audits.
The product’s strongest feature is its focused contrast workflow. Users can select colors directly from a webpage or enter hexadecimal values, then review the calculated ratio and WCAG status in the same pop-up. Alternative color suggestions provide a practical next step when a combination needs stronger contrast. The pop-up can be resized or minimized, which supports a less obstructive review process while working in a browser. According to the published plan, all listed capabilities are included in the Free plan at no cost, including the Chrome extension, contrast-ratio calculation, WCAG compliance checks, and alternative color suggestions.
Its narrow scope is also the main boundary. The extension addresses color contrast rather than broader accessibility scanning, reporting, integrations, or workflow management. That makes it a sensible choice for quick, targeted checks, but a limited fit for teams that need wider page audits or structured accessibility processes. Choose it if your priority is checking web color combinations in Chrome without a paid plan. Consider an alternative if your requirements extend beyond contrast review to broader scanning, reporting, integrations, or ongoing team workflows.
