Test Color Combinations for Contrast Ratio Scores

Use Venngage’s Color Contrast Checker to make sure the contrast between your text, icons, and background meets Web Content Accessibility Guidelines (WCAG) standards.

A user inputs different background colors into Venngage's WCAG Color Contrast Checker tool. There are widgets for the user to adjust foreground/text color, background color, lightness of both, and a section underneath that displays updated information about Contrast Ratio and Compliance Results, relative to WCAG Color Contrast guidelines, including whether the combinations pass or fail WCAG standards for color contrast and visibility.

Adjust color settings in Venngage’s WCAG Color Contrast Checker tool. The interface includes widgets to modify the foreground (text) color, background color, and their lightness levels. The tool instantly displays the Contrast Ratio and Compliance Results, showing whether the color combination passes or fails WCAG standards for visibility and accessibility.

How to use it:

Enter HEX Codes in the fields under each color widget to set your Foreground and Background colors.
Use the Lightness sliders to fine-tune the brightness or exposure of each color.
The Contrast Ratio section automatically updates to show your WCAG score.
Review the Compliance Results below to see whether your color combination meets accessibility requirements.
