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.
Teal is a split-complement of #5e503b: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
