Frost & Ember
Open in tool →Navy and frost with one ember red — the classic cold-with-a-warm-accent structure, borrowed from a thousand ski posters.
Color
#1d324ergb(29, 50, 78)hsl(214, 46%, 21%)oklch(0.314 0.057 256)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 is a split-complement of #1d324e: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Sea Green completes a triad with #1d324e — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Sienna sits directly opposite #1d324e on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Slate Blue is #1d324e's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Teal is #1d324e's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Amber is paired with #1d324e in 8 real palettes, including Beach Hut and McDonald's's brand system, as the supporting colour.
15 real palettes, including Minecraft's brand system and Monzo's brand system put Blue beside #1d324e, as the accent.
White Smoke is the surface for #1d324e: a clean near-white with no warm cast, so the cool hue stays clear instead of drifting muddy.

Fixes keep hue and saturation and move lightness only, so the suggestion stays on-brand. Ratios are symmetric: the same numbers apply with #1d324e as the background.
