- **Light Sea Green** #20b2aa [harmony: complementary] — Light Sea Green sits directly opposite #ff3399 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/lightseagreen
- **Medium Sea Green** #3cb371 [harmony, pool: split] — Medium Sea Green is a split-complement of #ff3399: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
