Overview
About this app
Huelab validates color pairings against WCAG 2.1 AA and AAA accessibility standards. Enter foreground and background hex colors to instantly see the computed contrast ratio and pass-fail badges for each compliance level. A live preview shows how text renders at multiple font weights with your chosen colors. Save approved pairs to build a personal palette library that persists across sessions. All calculations run in-browser with no external dependencies, making it fast and private for design teams reviewing color systems.
