- **Forest Green** #228b22 [harmony: split] — Forest Green is a split-complement of #681d45: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/forestgreen

- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #681d45: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. Seen in: Hinge (https://brandsweets.com/colors/brands/hinge-co). — https://brandsweets.com/colors/charcoal
- **Cream** #fffdd0 [role] — Cream is the surface #681d45 wants: a warm off-white that shares its undertone, so #681d45 reads softer on it than on pure white. — https://brandsweets.com/colors/cream
