## Colors that go with #b1398f

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 #b1398f on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.

- **Denim** #1560bd [pool] — Designers have shipped Denim with #b1398f: 4 real palettes, including Peacock and Hasbro's brand system, as the supporting colour.

- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #b1398f: 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 #b1398f: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/teal
- **Crimson** #dc143c [harmony, pool: analogous] — Crimson is #b1398f's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
