Colors that go with #fe5106
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 #fe5106: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Dodger Blue #1e90ff
split-complementshippedDodger Blue is a split-complement of #fe5106: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Cadet Blue #5f9ea0
complementaryshippedCadet Blue sits directly opposite #fe5106 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
