Colors that go with #01dff4
Charcoal, Dodger Blue and Taupe 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

Taupe #483c32

Salmon #fa8072
complementarySalmon sits directly opposite #01dff4 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Dark Orange #ff8c00
