Steel Blue, Crimson and Olive 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.
Steel Blue #4682b4
analogousshippedSteel Blue is Everlasting Night's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Crimson #dc143c
triadicshippedCrimson completes a triad with Everlasting Night — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Olive Green #808000
complementaryOlive Green sits directly opposite Everlasting Night on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Charcoal #36454f
neutralshippedCharcoal is the text near-black for Everlasting Night: softer than #000 and cool enough to feel like part of the same palette.
Orange Red #ff4500

Royal Blue #4169e1

Sienna #a0522d
split-complementSienna is a split-complement of Everlasting Night: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Blue #0000ff
shippedTwo real palettes: Pfizer's brand system and Procter & Gamble's brand system put Blue beside Everlasting Night, as the supporting colour.
