## Colors that go with #ef39bb

Named partners (harmony on the OKLCH wheel, co-occurrence in curated palettes and brand systems, and the neutrals that carry it), best first:

- **Medium Sea Green** #3cb371 [harmony, pool: complementary] — Medium Sea Green sits directly opposite #ef39bb on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight. Seen in: Terminal (https://brandsweets.com/palettes/technical#terminal). — https://brandsweets.com/colors/mediumseagreen
- **Light Sea Green** #20b2aa [harmony: split] — Light Sea Green is a split-complement of #ef39bb: 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 #ef39bb: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. — https://brandsweets.com/colors/charcoal
