#f75008rgb(247, 80, 8)hsl(18, 94%, 50%)oklch(0.658 0.213 37.8)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 #f75008 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 #f75008: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Dodger Blue is a split-complement of #f75008: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
