What is WCAG Contrast?

WCAG 2.2 requires text to have enough contrast for low vision users. In USA, failing this can lead to ADA lawsuits.

AA Standard: 4.5:1 for normal text, 3:1 for large text (18px+ or 14px bold)
AAA Standard: 7:1 for normal, 4.5:1 for large - best for government & healthcare sites.
