WCAG 2.2 contrast ratio: 4.71:1
WCAG 2.2 uses the same contrast formula as 2.1. Ratios are floored to two decimals, never rounded up.
| Text type | AA | AAA |
|---|---|---|
| Normal text | ✓ Pass | ✗ Fail |
| Large text (24px+, or 18.66px+ bold) | ✓ Pass | ✓ Pass |
| UI components and graphics | ✓ Pass | n/a |
APCA lightness contrast: Lc -54
Lc -54. Body text needs about Lc 75+, large text and UI about Lc 45+. Positive means dark text on a light background, negative means light text on dark.
Fixes via OKLCH lightness
The fix keeps hue and chroma and moves only OKLCH lightness to the nearest step that reaches the target for normal text, so it still looks like the same color. It is the same logic as the Fix button in the studio.
