Contrast Checker

CSS Peeper helps you stay aligned with the best accessibility practices by providing valuable insights into color contrast and its impact on readability. You can instantly assess contrast issues, ensuring your websites are beautiful and accessible. Accessibility features are available in Professional and Ultra plans.

When inspecting colors, CSS Peeper evaluates and displays accessibility scores that indicate how well (or poorly) certain color combinations meet accessibility standards. This feature uses the WCAG 2.0 (Web Content Accessibility Guidelines) to assess the contrast ratio and provide an accessibility score for each combination.

Accessibility score levels

CSS Peeper evaluates color contrast based on WCAG 2.0, helping you create designs that are clear and accessible to all users. We currently support four levels of accessibility assessment:

1. Excellent – All colors meet the highest accessibility standards, passing WCAG AA (4.5:1) and AAA (7:1) contrast requirements. Your design is fully optimized for readability and inclusivity.

2. Good – Colors meet the minimum WCAG AA standard (4.5:1), ensuring sufficient readability for most users. Your design is accessible but could be improved for enhanced clarity.

3. Poor – Colors only meet the basic contrast ratio (3:1), which is the absolute minimum for certain UI elements. This may cause readability issues for some users.

4. Very Poor – Colors fail all accessibility standards, making text difficult or impossible to read for many users. Immediate improvements are needed to ensure usability.

By incorporating these insights, you can create more inclusive designs that are accessible to a wider audience, improving usability for individuals with visual impairments or other disabilities. Keeping accessibility in mind ensures that your site is not only functional but also equitable and user-friendly for everyone.

Auto-Contrast Scanner

Designing for accessibility has never been this easy! The Automated Contrast Scanner on the Overview page instantly highlights color contrast issues, ensuring your designs meet accessibility standards. No more guessing – just clear insights at a glance. This feature is available exclusively for the Ultra plan subscribers.

Click on the Contrast Checker Card or the ‘Show All’ button to access a dedicated contrast page, where issues are neatly categorized for you.

On this page, contrast problems are grouped into two sections: Failing and Passing. The Failing section pinpoints poor accessibility color combinations that don’t meet WCAG standards, while the Passing section reassures you that your colors are working well.

With CSS Peeper, accessibility isn’t an afterthought—it’s built into your workflow. Stay compliant, create inclusive designs, and ensure every user experiences your work the way it’s meant to be!
