Contrast Ratio is a simple, web-based tool that calculates the color contrast ratio between two selected colors. It's built by Accessibility, a platform focused on digital inclusion. The tool helps designers and developers ensure their web content meets accessibility standards, specifically WCAG (Web Content Accessibility Guidelines) for text readability. For example, a designer could use it to test if the chosen font color on a particular background color provides sufficient contrast for visually impaired users to read easily.

Why It’s Useful
Ensuring web accessibility is crucial, and tools like Contrast Ratio make this task straightforward. While many design suites have built-in contrast checkers, this standalone web tool is incredibly accessible and easy to use, requiring no software installation. It provides immediate feedback on whether a color combination meets AA or AAA contrast requirements, a key factor for WCAG compliance. It's invaluable for anyone creating websites, user interfaces, or digital documents who wants to avoid common accessibility pitfalls. Developers often use it as a quick reference during mock-up stages, and content creators can verify their choice of text and background colors for blog posts or presentations.
