Colors that go with #331f19
Charcoal, Sienna and Slate 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.

Palettes built around it
Cider
Open in tool →Rust, honey and a moss green on cream — the orchard palette; the green keeps it from being all one temperature.
Desert Road
Open in tool →Sandstone and sand with a deep teal — the one cool note makes the warm colours look intentional rather than beige.
Kiln
Open in tool →Fired clay and ash on a dark umber — the earthy dark mode; warm enough that the dark surface reads as material, not void.
Darkroom
Open in tool →Sepia, faded ochre and a teal shadow on aged paper — the photograph-in-a-drawer palette, tuned so it still passes AA.
Sepia Mono
Open in tool →A single warm brown from espresso to oat — the sepia scale as a working palette, not a filter.
