- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #3a172e: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.

- **Dark Olive Green** #556b2f [harmony, pool: split] — Dark Olive Green is a split-complement of #3a172e: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
