Colors that go with Dark
Charcoal, Amber and Blue lead the list. Each partner is a real named colour with the reason it works — a wheel relationship, a neutral that carries it, or a pairing lifted from a palette or brand system that actually shipped — and every pair opens in the palette tool.

Contrast
| Dark as text | Ratio | AA | AA large | AAA | Fix |

Aaon white | 15.63:1 | pass | pass | pass | Passes AAA — no fix needed. |

Fixes keep hue and saturation and move lightness only, so the suggestion stays on-brand. Ratios are symmetric: the same numbers apply with Dark as the background.
