WCAG Contrast Checker
Check the contrast ratio between two colors against WCAG 2.2 thresholds. Accepts hex, rgb, or hsl in either field.
This checks one specific, measurable requirement — text/background contrast (WCAG 1.4.3). It is not a full accessibility audit: things like font size, keyboard navigation, and screen-reader support all matter too and aren't covered here.
Checked locally. Never sent anywhere.
