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

- **Denim** #1560bd [pool] — Designers have shipped Denim with #a4237f: 4 real palettes, including Peacock and Chase's brand system, as the supporting colour.

- **Sea Green** #2e8b57 [harmony: complementary] — Sea Green sits directly opposite #a4237f 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/seagreen
- **Forest Green** #228b22 [harmony, pool: split] — Forest Green is a split-complement of #a4237f: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. Seen in: Bun (https://brandsweets.com/colors/brands/bun-sh). — https://brandsweets.com/colors/forestgreen
- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #a4237f: 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
