- **Sea Green** #2e8b57 [harmony, pool: complementary] — Sea Green sits directly opposite #b4319e on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.

- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #b4319e: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. Seen in: Hasbro (https://brandsweets.com/colors/brands/hasbro-com). — https://brandsweets.com/colors/charcoal
- **Teal** #008080 [harmony: split] — Teal is a split-complement of #b4319e: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/teal
