- **Olive Drab** #6b8e23 [harmony: split] — Olive Drab is a split-complement of #f401b3: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/olivedrab
- **Charcoal** #36454f [role] — Charcoal is the body-text near-black for #f401b3: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. — https://brandsweets.com/colors/charcoal
