Colors that go with #efb806
Charcoal, Cornflower Blue 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 #36454f
neutralshippedCharcoal is the body-text near-black for #efb806: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Cornflower Blue #6495ed
complementaryshippedCornflower Blue sits directly opposite #efb806 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Deep Sky Blue #00bfff
split-complementshippedDeep Sky Blue is a split-complement of #efb806: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
