Colors that go with #bb4a11
Denim, Sea Green and Teal 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.
Denim #1560bd
split-complementshippedDenim is a split-complement of #bb4a11: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Sea Green #2e8b57
triadicshippedSea Green completes a triad with #bb4a11 — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Teal #008080
complementaryshippedTeal sits directly opposite #bb4a11 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
