#09c852rgb(9, 200, 82)hsl(143, 91%, 41%)oklch(0.727 0.209 148)Charcoal, Royal 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 is the body-text near-black for #09c852: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Royal Blue is paired with #09c852 in 6 real palettes, including Brilliant's brand system and Docker's brand system, as the accent.
Taupe is paired with #09c852 in 6 real palettes, including Obsidian's brand system and WhatsApp's brand system, as the text colour against it.
Fuchsia sits directly opposite #09c852 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Hot Pink is a split-complement of #09c852: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
3 real palettes, including Spotify's brand system and Unity's brand system put Blue beside #09c852, as the accent.
Cornflower Blue completes a triad with #09c852 — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Dark Orange shows up next to #09c852 in 3 real palettes, including Playground and Learning App, as the lead colour.

Point any MCP client at the shared colors endpoint and your agent gets the same engine as this page — direct_palette, edit_direction, check_palette, check_contrast — read-only, no key. Every direction it proposes comes with a /colors/d/… link: open it, lock what you like, paste the link back, and the agent edits rather than re-rolls.
