#230f06rgb(35, 15, 6)hsl(19, 71%, 8%)oklch(0.196 0.038 45.4)Charcoal, Sienna and Slate Blue 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 is the body-text near-black for #230f06: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Sienna is #230f06's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Slate Blue completes a triad with #230f06 — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Steel Blue is a split-complement of #230f06: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
