PairPass is a free measuring tool. These terms state, in plain language, what its results are and are not.
What the results are
Results are measurements: colour-contrast ratios computed from the WCAG 2.1 formula, verdicts against the thresholds of WCAG 2.1 criteria 1.4.3, 1.4.6 and 1.4.11, and exports and audit sheets derived from those measurements. The method and its test record are published on the methodology page so the measurements can be independently checked.
What the results are not
- Not a certification. No result, export or audit sheet from this site certifies or guarantees that any palette, product, website or service conforms to WCAG, complies with the European Accessibility Act, the ADA, or any other standard or law. Full conformance involves far more than colour contrast.
- Not legal advice. Summaries of regulation on this site are dated general information. Whether a law applies to your product or service is a question for your own legal adviser.
- Not an affiliation. PairPass is not part of, endorsed by, or affiliated with the W3C, WebAIM, or any standards or enforcement body. Standard names are used to cite the criteria applied.
Your responsibility
You are responsible for how you use the measurements — including checking pairings in their real context (real grounds, real states, real font sizes and weights) before relying on them, and for the accuracy of colours you enter. A pairing graded here was graded on the values provided, against the ground provided.
Availability and liability
The site is provided free, as is, without warranty of any kind. The operator's aim is that every number be right and checkable; if one is wrong, the correction route on the contact page is the remedy, and the published test record will be corrected. To the extent permitted by law, the operator is not liable for decisions made in reliance on the site's results.
The files you generate
Token files, exports and audit sheets you generate are yours to use in your projects without restriction. Their headers carry the boundary statement described on the audit sheet page; keeping that statement with the file keeps the record honest, and it travels with the file for a reason.
