- **Olive Drab** #6b8e23 [harmony: complementary] — Olive Drab sits directly opposite #bb40e7 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
- **Sea Green** #2e8b57 [harmony, pool: split] — Sea Green is a split-complement of #bb40e7: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. Seen in: Next.js (https://brandsweets.com/colors/brands/nextjs-org). — https://brandsweets.com/colors/seagreen
- **Charcoal** #36454f [role, pool] — Charcoal is the text near-black for #bb40e7: softer than #000 and cool enough to feel like part of the same palette. Seen in: Hasbro (https://brandsweets.com/colors/brands/hasbro-com). — https://brandsweets.com/colors/charcoal
