## Colors that go with #e137b1

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: complementary] — Medium Sea Green sits directly opposite #e137b1 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight. — https://brandsweets.com/colors/mediumseagreen
- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #e137b1: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. Seen in: Hasbro (https://brandsweets.com/colors/brands/hasbro-com). — https://brandsweets.com/colors/charcoal
- **Cadet Blue** #5f9ea0 [harmony: split] — Cadet Blue is a split-complement of #e137b1: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/cadetblue
- **Olive Drab** #6b8e23 [harmony: split] — Olive Drab is a split-complement of #e137b1: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/olivedrab
