- **Sea Green** #2e8b57 [harmony: complementary] — Sea Green sits directly opposite #c91d8f 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
- **Dark Cyan** #008b8b [harmony, pool: split] — Dark Cyan is a split-complement of #c91d8f: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. Seen in: Peacock (https://brandsweets.com/palettes/vivid#peacock). — https://brandsweets.com/colors/darkcyan
