#292d4crgb(41, 45, 76)hsl(233, 30%, 23%)oklch(0.309 0.056 277)Dark Olive Green, Sea Green 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.
Dark Olive Green sits directly opposite #292d4c on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Sea Green completes a triad with #292d4c — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Sienna is a split-complement of #292d4c: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
