#1bc063rgb(27, 192, 99)hsl(146, 75%, 43%)oklch(0.709 0.183 151.4)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 text near-black for #1bc063: softer than #000 and cool enough to feel like part of the same palette.
Royal Blue is paired with #1bc063 in 5 real palettes, including Brilliant's brand system and Khan Academy's brand system, as the accent.
Taupe is paired with #1bc063 in 9 real palettes, including Obsidian's brand system and Chime's brand system, as the text colour against it.
Fuchsia sits directly opposite #1bc063 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 #1bc063: 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 #1bc063, as the accent.
Cornflower Blue completes a triad with #1bc063 — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Dark Olive Green shows up next to #1bc063 in 3 real palettes, including Undergrowth and Forest Floor, as the supporting colour.

Aaon black | 8.77:1 | 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 #1bc063 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.
