#eccf51rgb(236, 207, 81)hsl(49, 80%, 62%)oklch(0.856 0.146 96.1)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.
Deep Sky Blue is a split-complement of #eccf51: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Lilac sits directly opposite #eccf51 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
