#03ce98rgb(3, 206, 152)hsl(164, 97%, 41%)oklch(0.755 0.157 165.8)Charcoal, Hot Pink and Deep Sky 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 text near-black for #03ce98: softer than #000 and cool enough to feel like part of the same palette.
Hot Pink sits directly opposite #03ce98 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Designers have shipped Deep Sky Blue with #03ce98: 4 real palettes, including Remix's brand system and Prime Video's brand system, as the lead colour.
4 real palettes, including Fresh Juice and Crayon Box put Mustard Yellow beside #03ce98, as the supporting colour.
Taupe is paired with #03ce98 in 12 real palettes, including WhatsApp's brand system and Obsidian's brand system, as the supporting colour.
Light Coral is a split-complement of #03ce98: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Crimson is paired with #03ce98 in 3 real palettes, including DuckDuckGo's brand system and Formula 1's brand system, as the supporting colour.
Dark Olive Green shows up next to #03ce98 in 3 real palettes, including 7-Eleven's brand system and Undergrowth, as the supporting 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.
