How to check any pair

  1. Enter two colours

    Type a hex, rgb or hsl value, use the colour picker, or pick any pixel on your screen where the browser supports it.

  2. Read the verdict

    The ratio and five badges update as you type. Each badge says pass or fail for one WCAG level.

  3. Check the specimen

    See your colours as normal text, large text, a button outline and an icon, exactly as a visitor would.

  4. Fix a failing pair

    Pick a target ratio and apply the closest passing colour. Only lightness changes, so your hue stays recognisable. A colour-blindness preview shows how the pair holds up for other eyes.

  5. Share or compare

    Copy the result as text, CSS or an image, or copy a link that opens the same colours. Switch to grid mode to compare up to eight colours at once.
