Blue Violet, Charcoal and Royal 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.
Blue Violet #8a2be2
complementaryshippedBlue Violet sits directly opposite #181e01 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
