Color Contrast Checker

Ensure your website is accessible to everyone with our Color Contrast Checker. This tool calculates the contrast ratio between two colors based on the Web Content Accessibility Guidelines (WCAG).

Sufficient contrast is essential for users with visual impairments, color blindness, or those viewing screens in bright sunlight.

Understanding WCAG Standards

• Level AA: The standard level of accessibility. Requires a ratio of at least 4.5:1 for normal text and 3:1 for large text.
• Level AAA: The highest level of accessibility. Requires a ratio of at least 7:1 for normal text and 4.5:1 for large text.

How to Use

1. Select a foreground color (text color).
2. Select a background color.
3. The tool instantly calculates the ratio and shows Pass/Fail grades for different WCAG levels.
4. Check the preview box to see how the text looks in real life.

Why is this important?

Accessibility is not just a nice-to-have; it's a legal requirement in many jurisdictions. Moreover, good contrast improves readability for all users, leading to a better user experience and higher engagement.
