Colors that go with Midnight Monarch
Charcoal, Dark Olive Green 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.
Charcoal #36454f
neutralshippedCharcoal is the text near-black for Midnight Monarch: softer than #000 and cool enough to feel like part of the same palette.
Dark Olive Green #556b2f
complementaryshippedDark Olive Green sits directly opposite Midnight Monarch on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Royal Blue #4169e1
analogousshippedRoyal Blue is Midnight Monarch's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Sea Green #2e8b57
split-complementshippedSea Green is a split-complement of Midnight Monarch: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Sienna #a0522d

Teal #008080
