A11Y-CONTRASTDeterministic
Text meets minimum contrast against its background
What the source requires
Text must meet a minimum contrast ratio against its background.
Why this is hard to satisfy
The site was delivered and the design firm moved on. There is no developer to change a colour.
What we do about it
Measured, reported with the exact ratio and the failing pair, and corrected in generated assets.

What this tier means
