Colors that go with #301d18
Charcoal, Sea Green and Sienna 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 #008080

Palettes built around it
Harvest
Open in tool →Pumpkin, straw and burnt gold on parchment — the autumn palette that still feels like a product, not a place-mat.
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.
Candlelight
Open in tool →Burgundy, gold and a blush on warm white — the evening wedding set; burgundy carries the formality, blush the softness.
