Colors that go with Calypso
Charcoal, Denim and Sienna 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 Calypso: softer than #000 and cool enough to feel like part of the same palette.
Denim #1560bd
analogousshippedDenim is Calypso's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Sienna #a0522d
complementaryshippedSienna sits directly opposite Calypso on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
