Taupe, Medium Orchid and Medium Purple 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 #3bb512 in 5 real palettes, including Obsidian's brand system and Meadow, as the text colour against it.
Medium Orchid #ba55d3
complementaryMedium Orchid sits directly opposite #3bb512 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Medium Purple #9370db
split-complementshippedMedium Purple is a split-complement of #3bb512: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Charcoal #36454f
neutralshippedCharcoal is the body-text near-black for #3bb512: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
