| Sinister as text | Ratio | AA | AA large | AAA | Fix |
|---|---|---|---|---|---|
Aaon white | 18.88:1 | pass | pass | pass | Passes AAA — no fix needed. |
Aaon black | 1.11:1 | fail | fail | fail |
Fixes keep hue and saturation and move lightness only, so the suggestion stays on-brand. Ratios are symmetric: the same numbers apply with Sinister as the background.
