Admin Color Contrast Checker

About this Plugin

An admin-only tool that calculates the WCAG 2.1 contrast ratio for any foreground/background colour pair. Enter hex values or use the colour picker, click Check, and instantly see pass/fail badges for AA Normal, AA Large, AAA Normal, and AAA Large. A live preview renders sample text on the chosen background so you can see the result visually before applying it to your theme.
