Colors that go with #efc64e
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 #efc64e: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Cornflower Blue #6495ed
complementaryshippedCornflower Blue sits directly opposite #efc64e on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
