- **Medium Violet Red** #c71585 [harmony: split] — Medium Violet Red is a split-complement of #03540b: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/mediumvioletred
- **Cream** #fffdd0 [role] — Cream is the surface #03540b wants: a warm off-white that shares its undertone, so #03540b reads softer on it than on pure white. — https://brandsweets.com/colors/cream
