#604b2frgb(96, 75, 47)hsl(34, 34%, 28%)oklch(0.428 0.051 73.8)Teal, Steel Blue and Champagne 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 #604b2f: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Steel Blue sits directly opposite #604b2f 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 Darkroom and BrandSweets's brand system put Champagne beside #604b2f, as the surface under it.
Designers have shipped Copper with #604b2f: 5 real palettes, including Desert Road and Bakery, as the lead colour.
Designers have shipped Denim with #604b2f: 4 real palettes, including HP's brand system and Hinge's brand system, as the accent.
Royal Blue is paired with #604b2f in 4 real palettes, including Console Light and GitHub's brand system, as the lead colour.
Designers have shipped Sage Green with #604b2f: 7 real palettes, including Darkroom and Oatmeal, as the supporting colour.
Cream is the surface #604b2f wants: a warm off-white that shares its undertone, so #604b2f reads softer on it than on pure white.

Aaon white | 8.25:1 | pass | pass | pass | Passes AAA — no fix needed. |

Fixes keep hue and saturation and move lightness only, so the suggestion stays on-brand. Ratios are symmetric: the same numbers apply with #604b2f as the background.
