What is a color contrast checker?

A color contrast checker helps verify if the contrast between text and background meets accessibility standards like WCAG AA or AAA.

What is a good contrast ratio?

For normal text, a contrast ratio of at least 4.5:1 is recommended (AA level). For large text, 3:1 is acceptable. AAA level requires 7:1 for normal text.
