- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #340f21: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.

- **Teal** #008080 [harmony, pool: complementary] — Teal sits directly opposite #340f21 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
