#5f4e3frgb(95, 78, 63)hsl(28, 20%, 31%)oklch(0.437 0.033 63.2)Teal, Steel Blue and 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.
Teal is a split-complement of #5f4e3f: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Steel Blue sits directly opposite #5f4e3f on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
4 real palettes, including Warp's brand system and Jeep's brand system put Blue beside #5f4e3f, as the supporting colour.
5 real palettes, including Darkroom and BrandSweets's brand system put Champagne beside #5f4e3f, as the surface under it.
Designers have shipped Copper with #5f4e3f: 6 real palettes, including Desert Road and Bakery, as the lead colour.
Designers have shipped Denim with #5f4e3f: 4 real palettes, including HP's brand system and Hinge's brand system, as the accent.
4 real palettes, including Bakery and Paper & Pine put Peru beside #5f4e3f, as the supporting colour.
Cream is the surface #5f4e3f wants: a warm off-white that shares its undertone, so #5f4e3f reads softer on it than on pure white.
