Legibly

Legibly checks color contrast the moment you pick a color — no account, no internet, no waiting for a web tool to load. Pick a foreground and background with the color picker, hex entry, or a built-in eyedropper that samples a color straight from any photo in your library. Legibly instantly shows the WCAG 2.x contrast ratio with AA/AAA pass badges for normal text, large text, and UI components, plus a live text preview so you can see exactly how legible your pairing really is. Designers and developers use Legibly to sanity-check a brand palette before it ships, catch a low-contrast button during a design review, or verify a color pairing meets accessibility guidelines without leaving their phone.
