#0e353ergb(14, 53, 62)hsl(191, 63%, 15%)oklch(0.306 0.045 216.1)Crimson, Rust 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.
Crimson is a split-complement of #0e353e: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Rust sits directly opposite #0e353e on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Sienna is a split-complement of #0e353e: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Steel Blue is #0e353e's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.

15 real palettes, including Instacart's brand system and Headspace's brand system put Blue beside #0e353e, as the accent.
White Smoke is the surface for #0e353e: a clean near-white with no warm cast, so the cool hue stays clear instead of drifting muddy.
