Color
#ef4f1argb(239, 79, 26)hsl(15, 87%, 52%)oklch(0.644 0.205 36.7)Cadet Blue, Charcoal and Dodger 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.
Cadet Blue sits directly opposite #ef4f1a on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Charcoal is the body-text near-black for #ef4f1a: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Dodger Blue is a split-complement of #ef4f1a: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Amber is paired with #ef4f1a in 7 real palettes, including Ember and Heatwave, as the accent.
8 real palettes, including Glossier's brand system and Readymag's brand system put Blue beside #ef4f1a, as the accent.
Designers have shipped Cobalt Blue with #ef4f1a: 5 real palettes, including Tide's brand system and NASA's brand system, as the lead colour.
Designers have shipped Denim with #ef4f1a: 15 real palettes, including PlanetScale's brand system and Postman's brand system, as the accent.
Designers have shipped Firebrick with #ef4f1a: 8 real palettes, including Ember and 3M's brand system, 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.
