Colors that go with #c3fd08
Plum, Violet and Charcoal 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.
Plum #dda0dd
complementaryPlum sits directly opposite #c3fd08 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Violet #ee82ee
