## Colors that go with #ef39af

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 #ef39af 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
- **Tomato** #ff6347 [harmony, pool: analogous] — Tomato is #ef39af's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces. Seen in: Night Market (https://brandsweets.com/palettes/vivid#night-market), Sunset Boulevard (https://brandsweets.com/palettes/warm#sunset-boulevard). — https://brandsweets.com/colors/tomato
- **Cadet Blue** #5f9ea0 [harmony: split] — Cadet Blue is a split-complement of #ef39af: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/cadetblue
- **Charcoal** #36454f [role] — Charcoal is the body-text near-black for #ef39af: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. — https://brandsweets.com/colors/charcoal

- **Dark Goldenrod** #b8860b [harmony: triadic] — Dark Goldenrod completes a triad with #ef39af — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash. — https://brandsweets.com/colors/darkgoldenrod
