PASS means your color combination meets WCAG 2.1 guidelines at that level. Text is readable for most users, including those with low vision (approximately 20/40 vision).
FAIL means the contrast is insufficient. Users with low vision or viewing in bright environments may struggle to read the text. Consider darkening the foreground or lightening the background.
Remember: WCAG AA is the legal standard for most websites (Section 508, EN 301 549). AAA is a higher goal but not always achievable — and that's okay.
Enter hex values (one per line or comma-separated) to generate a contrast matrix.
