Colors that go with #fb4d0e
Charcoal, Dodger Blue and Cadet 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 #36454f
neutralshippedCharcoal is the body-text near-black for #fb4d0e: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Dodger Blue #1e90ff

Cadet Blue #5f9ea0
