- **Sea Green** #2e8b57 [harmony: complementary] — Sea Green sits directly opposite #c40397 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/seagreen
- **Forest Green** #228b22 [harmony, pool: split] — Forest Green is a split-complement of #c40397: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. Seen in: Bun (https://brandsweets.com/colors/brands/bun-sh). — https://brandsweets.com/colors/forestgreen
