Taupe, Violet 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 #42db3d in 8 real palettes, including WhatsApp's brand system and 7-Eleven's brand system, as the supporting colour.
Violet #ee82ee
complementaryViolet sits directly opposite #42db3d 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 #42db3d: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Blue #0000ff
shipped3 real palettes, including MongoDB's brand system and Minecraft's brand system put Blue beside #42db3d, as the accent.
Charcoal #36454f

Cornflower Blue #6495ed
