Taupe, Orchid and Hot Pink 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.
Taupe #483c32
shippedTaupe is paired with #40bd0f in 5 real palettes, including Obsidian's brand system and Meadow, as the text colour against it — a combination designers have actually shipped, not a computed rotation.
Orchid #da70d6
complementaryOrchid sits directly opposite #40bd0f on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Hot Pink #ff69b4
split-complementshippedHot Pink is a split-complement of #40bd0f: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Medium Purple #9370db

Charcoal #36454f
