Colors that go with #efc55d
Charcoal, Deep Sky Blue and Lilac 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.
