- **Cadet Blue** #5f9ea0 [harmony: complementary] — Cadet Blue sits directly opposite #ef159f 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/cadetblue

Seen in: Night Market (https://brandsweets.com/palettes/vivid#night-market), Sunset Boulevard (https://brandsweets.com/palettes/warm#sunset-boulevard), Airbnb (https://brandsweets.com/colors/brands/airbnb). — https://brandsweets.com/colors/tomato
- **Olive Drab** #6b8e23 [harmony: split] — Olive Drab is a split-complement of #ef159f: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/olivedrab
- **Charcoal** #36454f [role] — Charcoal is the body-text near-black for #ef159f: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. — https://brandsweets.com/colors/charcoal
