#3cb456rgb(60, 180, 86)hsl(133, 50%, 47%)oklch(0.682 0.17 147.4)Charcoal, Mustard Yellow and Royal Blue 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 #3cb456: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
4 real palettes, including Meadow and Citrus Grove put Mustard Yellow beside #3cb456, as the supporting colour.
Royal Blue is paired with #3cb456 in 5 real palettes, including Console Light and Telehealth, as the lead colour.
Taupe is paired with #3cb456 in 6 real palettes, including Obsidian's brand system and Meadow, as the text colour against it.
Fuchsia sits directly opposite #3cb456 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 #3cb456: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Medium Purple is a split-complement of #3cb456: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Cornflower Blue completes a triad with #3cb456 — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.

Aaon black | 7.86:1 | pass | pass | pass | Passes AAA — no fix needed. |
Fixes keep hue and saturation and move lightness only, so the suggestion stays on-brand. Ratios are symmetric: the same numbers apply with #3cb456 as the background.
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.
