Welcome to our Color Contrast Checker, a free, simple, and easy-to-use online tool that helps you test the color contrast ratio of any two colors in real-time. This tool is available for you to use anytime, to ensure your content is accessible and compliant with WCAG guidelines.
Color contrast in Accessibility or 508 compliance is measured as the difference in perceived 'luminance' or brightness between two colors. This brightness difference between the background color and the foreground color on a website is expressed as a ratio ranging from 1:1 (for white on white) to 21:1 (for black on white). Learn More
Our Color Contrast Checker takes two color inputs in the form of hex codes. It then calculates the contrast ratio between these colors and indicates whether the contrast ratio passes the WCAG standards for accessibility of color contrast for AA and AAA level texts. Learn More
Improving the color contrast ratio can be achieved by increasing the contrast between the foreground and the background color to at least 4.5:1. You can check the color contrast ratio using our color contrast checker. Learn More
We have a series of blog articles that delve into color contrast and accessibility in more detail:
Whether you're a web developer looking to ensure your website is accessible, a designer aiming to create visually appealing and accessible designs, or a content creator needing to ensure your content is accessible to all, our Color Contrast Checker tool and accompanying resources have got you covered.
