#fdfd12rgb(253, 253, 18)hsl(60, 98%, 53%)oklch(0.962 0.208 109.7)Lilac, Violet and Deep Sky 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.
Lilac sits directly opposite #fdfd12 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Violet is a split-complement of #fdfd12: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Deep Sky Blue is a split-complement of #fdfd12: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
3 real palettes, including Robinhood's brand system and Bumble's brand system put Blue beside #fdfd12, as the supporting colour.
Charcoal is the body-text near-black for #fdfd12: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
3 real palettes, including Arcade and JetBrains's brand system put Deep Pink beside #fdfd12, as the lead colour.
Amber is paired with #fdfd12 in two real palettes: Gumroad's brand system and Binance's brand system, as the accent.
Crimson is paired with #fdfd12 in two real palettes: Lay's's brand system and Tequila Sunrise, as the accent.

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.
