An online tool that evaluates the contrast ratio between text and background colors to ensure compliance with WCAG accessibility standards.

Pros

  • Simple and straightforward interface
  • Can save colors

Cons

  • No quick ways to generate tints and shades

Colour Contrast Checker is a straightforward online tool designed to help designers assess the contrast between text and background colors, ensuring they meet the Web Content Accessibility Guidelines (WCAG). By inputting specific color values, users can quickly determine if their color combinations adhere to accessibility standards. The tool provides immediate feedback on whether the selected colors pass or fail various WCAG levels, such as AA and AAA, for both normal and large text. This functionality is particularly useful for creating designs that are accessible to individuals with visual impairments.

In addition to the web-based tool, Colour Contrast Checker offers a Chrome extension, allowing users to evaluate color contrasts directly within their browser. This extension facilitates on-the-fly assessments of web pages, enhancing workflow efficiency for designers and developers.

While the tool is effective for quick checks, it’s important to note that it may not account for all contextual factors affecting readability, such as font choice or surrounding design elements. Therefore, it’s advisable to use Colour Contrast Checker as part of a comprehensive accessibility evaluation process.
