What is a good color contrast ratio?

According to WCAG (Web Content Accessibility Guidelines), a good contrast ratio is at least 4.5:1 for normal text and 3:1 for large text to meet AA standards. For the stricter AAA standard, you need 7:1 for normal text and 4.5:1 for large text.

Why is color contrast important?

Adequate color contrast ensures that text is readable by everyone, including people with visual impairments or color vision deficiencies. It is a critical component of web accessibility and inclusive design.
