#3a511argb(58, 81, 26)hsl(85, 51%, 21%)oklch(0.403 0.085 128.9)Blue, Crimson and Emerald Green 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.
5 real palettes, including Rolex's brand system and Warp's brand system put Blue beside #3a511a, as the accent.

Dark Orchid sits directly opposite #3a511a on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Cream is the surface #3a511a wants: a warm off-white that shares its undertone, so #3a511a reads softer on it than on pure white.
