- **Olive Drab** #6b8e23 [harmony: complementary] — Olive Drab sits directly opposite #d31bf3 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/olivedrab

- **Cadet Blue** #5f9ea0 [harmony: split] — Cadet Blue is a split-complement of #d31bf3: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/cadetblue
