- **Medium Sea Green** #3cb371 [harmony: complementary] — Medium Sea Green sits directly opposite #ef1aa1 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
- **Cadet Blue** #5f9ea0 [harmony: split] — Cadet Blue is a split-complement of #ef1aa1: 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 #ef1aa1: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/olivedrab
