Colors that go with Grotesque Green
Charcoal, Deep Sky Blue and Taupe 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.
Charcoal #36454f
neutralshippedCharcoal is the body-text near-black for Grotesque Green: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.

shippedDesigners have shipped Deep Sky Blue with Grotesque Green: 4 real palettes, including Remix's brand system and Prime Video's brand system, as the lead colour.
Taupe #483c32
shippedTaupe is paired with Grotesque Green in 10 real palettes, including 7-Eleven's brand system and Astro's brand system, as the lead colour.
Violet #ee82ee
complementaryViolet sits directly opposite Grotesque Green on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Light Coral #f08080
