WCAG Contrast Checker for Accessible Design

Contrast checkers help ensure that text and background color combinations meet accessibility standards defined by WCAG. Proper contrast improves readability for users with visual impairments.

Accessible color design is critical for modern websites and applications. Using contrast tools early in the design process prevents usability issues and ensures compliance with accessibility guidelines.

This guide helps designers understand AA and AAA contrast ratios and apply them effectively in UI design.

Why This Matters

Over 2.2 billion people have a vision impairment. If your text doesn't have enough contrast against its background, millions of users simply cannot read your content. Ensuring WCAG compliance is not just about legality; it's about inclusivity and good user experience.

Frequently Asked Questions

What is the minimum contrast ratio?

For normal text (body copy), the minimum ratio for AA level is 4.5:1. For large text (headings), it is 3:1.

What if my brand colors fail contrast checks?

You don't have to change your logo. However, for UI elements like buttons or text, you should adjust the lightness of the background or text color until it passes. Often a slight tweak is all that is needed.
