- **Light Sea Green** #20b2aa [harmony: split] — Light Sea Green is a split-complement of #ef43d8: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/lightseagreen
- **Charcoal** #36454f [role] — Charcoal is the body-text near-black for #ef43d8: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. — https://brandsweets.com/colors/charcoal
