Disclosure

Transparency about links and funding, per FTC guidance.

a11ycontrast is free. Some outbound links — for example to accessibility-audit or design tools — may be affiliate links: if you sign up through them we may earn a commission at no extra cost to you. Paid links are marked rel="sponsored nofollow".

We only link to tools we’d actually use, and a commission never changes what we recommend or what the auditor reports. The contrast results are computed purely from the colors you paste — not from who pays us.

a11ycontrast runs entirely in your browser and keeps no logs of the colors you check.
