Named partners (harmony on the OKLCH wheel, co-occurrence in curated palettes and brand systems, and the neutrals that carry it), best first:

- **Sea Green** #2e8b57 [harmony, pool: complementary] — Sea Green sits directly opposite #b643a7 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.

- **Dark Cyan** #008b8b [harmony, pool: split] — Dark Cyan is a split-complement of #b643a7: 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
- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #b643a7: 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
