Colour Contrast Checker

Colour Contrast Checker is a web-based tool aimed at assisting designers, developers, and anyone interested in ensuring to assist in evaluating the contrast between two color combinations against the Web Content Accessibility Guidelines (WCAG) standards. Ensuring an adequate color contrast is crucial for making web content accessible to individuals with visual impairments, including color blindness.

Here's a breakdown of what the tool offers and how it helps in adhering to WCAG standards:

Colour Contrast Checker Functionality:

  1. Accessibility Compliance Checking:

    • The tool allows you to check color combinations for compliance with WCAG standards for color contrast. It can evaluate color pairs for both AA and AAA levels of compliance.

  2. Online and Extension Versions:

    • Besides the online version, it is also available as a Chrome extension, making it convenient to check color contrasts while browsing or designing web pages.

  3. Ease of Use for Designers and Developers:

    • It facilitates designers and developers in easily determining if the text and background colors they have selected meet the required contrast ratio for accessibility.


  • Promoting Inclusivity:

    • By helping to ensure that color contrasts meet accessibility standards, the tool promotes the creation of more inclusive digital content, which is crucial for individuals with visual impairments.

  • Enhancing User Experience (UX):

    • Adequate color contrast is not only about accessibility; it also significantly impacts the overall user experience by enhancing readability and comprehension.


  • It's fairly straightforward to use. You would typically input the color values of the text and the background, and the tool would then evaluate the contrast ratio against the WCAG standards, indicating whether the color combination is compliant.


  • The Colour Contrast Checker is freely available online, making it an easily accessible resource for anyone looking to ensure their website's color scheme is accessible and compliant with WCAG standards.

This tool can be a valuable asset for web developers, designers, and anyone else interested in ensuring their digital content is accessible to as wide an audience as possible.
