Palette Bench

Build a six-color palette, compare text contrast and export CSS variables or JSON. Runs offline and includes source.

Edit six hex colors using the color fields. Select foreground and background to compute WCAG contrast. AA normal text uses 4.5:1, AA large text uses 3:1. Contrast alone does not establish full accessibility compliance. Export CSS or JSON; Save keeps the palette locally.

Extract the ZIP and open index.html. Includes readable HTML, CSS and JavaScript, README and personal or commercial reuse permission. No installation or online account required. Built with AI-assisted code; no exclusive copyright promised. Tested in Chromium. Mobile layout and other browsers have not been verified.
