Colors that go with Dark Eclipse
Charcoal, Dark Olive Green and Sea Green 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 Dark Eclipse: softer than #000 and cool enough to feel like part of the same palette.
Dark Olive Green #556b2f
split-complementshippedDark Olive Green is a split-complement of Dark Eclipse: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Sea Green #2e8b57
triadicshippedSea Green completes a triad with Dark Eclipse — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Sienna #a0522d
complementaryshippedSienna sits directly opposite Dark Eclipse on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Slate Blue #6a5acd
analogousshippedSlate Blue is Dark Eclipse's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Steel Blue #4682b4
analogousshippedSteel Blue is Dark Eclipse's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
