Randoma11y is a free, real-time playground that generates random foreground/background color pairs and checks them against WCAG and APCA contrast standards, previewed live on buttons, badges, and text.
Combinations render on actual UI elements (not merely flat swatches side by side), and both WCAG 2.1 and the newer APCA algorithm are shown at once, so a pairing can be checked against whichever standard a project actually needs to meet.
Designers hunting for an accessible color pairing by browsing live examples rather than manually testing swatches one at a time in a separate contrast checker.
Vote on combinations while browsing. It's a crowdsourced feature that helps the archive surface pairings that are both accessible and actually good-looking, not merely technically compliant.
Generate beautiful colour palettes that are also accessibility-friendly.
