#45313argb(69, 49, 58)hsl(333, 17%, 23%)oklch(0.339 0.032 350.3)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 completes a triad with #45313a — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Sea Green is a split-complement of #45313a: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Sienna is #45313a's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Teal sits directly opposite #45313a on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
10 real palettes, including Dunkin''s brand system and Headspace's brand system put Blue beside #45313a, as the supporting colour.
5 real palettes, including Garden Wedding and Blush put Blush Pink beside #45313a, as the supporting colour.
Burlywood is paired with #45313a in 5 real palettes, including Polaroid and Coastal, as the accent.
Cream is the surface #45313a wants: a warm off-white that shares its undertone, so #45313a reads softer on it than on pure white.
