#f2fc3brgb(242, 252, 59)hsl(63, 97%, 61%)oklch(0.953 0.197 112.7)Blue, Crimson and Taupe 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.
4 real palettes, including Snapchat's brand system and Robinhood's brand system put Blue beside #f2fc3b, as the supporting colour.
Crimson is paired with #f2fc3b in 6 real palettes, including Ferrari's brand system and Lay's's brand system, as the lead colour.
Taupe is paired with #f2fc3b in 6 real palettes, including Calvin Klein's brand system and Tommy Hilfiger's brand system, as the lead colour.
Violet is a split-complement of #f2fc3b: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Plum sits directly opposite #f2fc3b on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Charcoal is the body-text near-black for #f2fc3b: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Cornflower Blue is a split-complement of #f2fc3b: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
3 real palettes, including Arcade and JetBrains's brand system put Deep Pink beside #f2fc3b, as the lead colour.
| #f2fc3b as text | Ratio | AA | AA large | AAA | Fix |

Aaon white | 1.12:1 | fail | fail | fail | |
Aaon black | 18.76:1 | 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 #f2fc3b as the background.
Point any MCP client at the shared colors endpoint and your agent gets the same engine as this page — direct_palette, edit_direction, check_palette, check_contrast — read-only, no key. Every direction it proposes comes with a /colors/d/… link: open it, lock what you like, paste the link back, and the agent edits rather than re-rolls.
