Why use a contrast checker?
Good readability is essential for any professional web design. With our free Contrast Checker, you can easily verify whether your chosen color combination meets the WCAG guidelines for digital accessibility. These guidelines are important to make your website readable for everyone – including people with visual impairments.
The tool automatically calculates the contrast ratio between foreground and background color and indicates whether it meets level AA or AAA. That way, you know your content is clearly visible on any screen and for every user.
In addition to the contrast analysis, our tool also shows the corresponding HEX, RGB, and CMYK values of your colors. This is useful for both developers and graphic designers who work with different software or print colors. Thanks to the built-in color picker, there’s no need to memorize codes – just select your color and see the result instantly.
Whether you're working on a website, mobile app or branding project, this color tool helps you quickly and visually make the right color choices. Completely free and installation-free, ready to use directly in your browser.
