Violet, Charcoal 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.
Violet #ee82ee
complementaryshippedViolet sits directly opposite #9bf221 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Charcoal #36454f

Blue #0000ff
shippedBlue is paired with #9bf221 in two real palettes: Robinhood's brand system and MongoDB's brand system, as the supporting colour — a combination designers have actually shipped, not a computed rotation.
