Charcoal, Deep Sky Blue and Light Coral 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
neutralshippedCharcoal is the text near-black for #3fdbe4: softer than #000 and cool enough to feel like part of the same palette.
Deep Sky Blue #00bfff
analogousshippedDeep Sky Blue is #3fdbe4's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Light Coral #f08080
complementaryshippedLight Coral sits directly opposite #3fdbe4 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
