Blue, Taupe and Medium Orchid 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.
Blue #0000ff
shipped4 real palettes, including Spotify's brand system and Minecraft's brand system put Blue beside #39ad0b, as the accent.
Taupe #483c32
shippedTaupe is paired with #39ad0b in 9 real palettes, including Obsidian's brand system and Acer's brand system, as the text colour against it.
Medium Orchid #ba55d3
complementaryMedium Orchid sits directly opposite #39ad0b 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 #39ad0b: 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 #39ad0b: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Cornflower Blue #6495ed
triadicshippedCornflower Blue completes a triad with #39ad0b — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.

Dodger Blue #1e90ff
