#37531drgb(55, 83, 29)hsl(91, 48%, 22%)oklch(0.407 0.087 132.2)Charcoal, Crimson and Orange Red 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 #37531d: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
