Black or white text?

Black text 16.75:1 — AA normal text passes
White text 1.25:1 — AA normal text fails

AA normal text: black passes; white fails.

AA large text: black passes; white fails.

WCAG contrast thresholds use 4.5:1 for normal text and 3:1 for large text. Do not round a near-threshold result upward when testing conformance.
