#57d016rgb(87, 208, 22)hsl(99, 81%, 45%)oklch(0.758 0.23 138.3)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 is paired with #57d016 in 8 real palettes, including Minecraft's brand system and WhatsApp's brand system, as the lead colour.
Violet sits directly opposite #57d016 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 #57d016: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
3 real palettes, including Minecraft's brand system and MongoDB's brand system put Blue beside #57d016, as the accent.
Charcoal is the body-text near-black for #57d016: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Dark Orange shows up next to #57d016 in 3 real palettes, including Learning App and Playground, as the accent.
Deep Sky Blue completes a triad with #57d016 — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
3 real palettes, including Meadow and Citrus Grove put Mustard Yellow beside #57d016, as the supporting colour.

Aaon white | 2.01:1 | fail | fail | fail | |
Aaon black | 10.44:1 | 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 #57d016 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.
