Understanding Color Contrast

A Contrast Checker is vital for inclusive design. It ensures your text is readable for everyone, including people with low vision or color blindness.

This tool uses relative luminance to calculate ratios. Level AA requires 4.5:1 for normal text, while AAA requires 7:1. Adjust colors on the left to see results on the right instantly.
