Make sure your marketing colours meet WCAG (Web Content Accessibility Guidelines) with our easy-to-use colour checker. Simply input your text and background colours in HEX or RGB or use the colour picker tool. Instantly see the contrast results on the right side of the tool, along with actionable recommendations on improving your contrast for better accessibility compliance.
With the right contrast, your content becomes more readable for users with visual impairments, improving their overall experience. The tool helps you achieve WCAG AA and AAA compliance levels, so you can be confident that your content is accessible to a broader audience.
Web accessibility isn’t just about following guidelines; it’s about ensuring everyone, including people with disabilities, can access and navigate your content. By improving colour contrast and meeting WCAG standards, you’ll enhance the user experience for all visitors, increase engagement, and avoid potential legal challenges.
