Quick pairs

WCAG measures the luminance ratio between text and background, from 1:1 (invisible) to 21:1 (black on white). AA needs 4.5:1 for normal text and 3:1 for large text (18pt+, or 14pt bold). AAA raises those to 7:1 and 4.5:1.

Busywork like this is what we automate.

The checks you run every month, the reports you rebuild every week. We set up an agent to do the repetitive part, a person on our team supervises it, and everything runs in accounts you own.
