## Colors that go with #b51cab

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: complementary] — Sea Green sits directly opposite #b51cab 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
- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #b51cab: 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
- **Denim** #1560bd [pool] — Designers have shipped Denim with #b51cab: 3 real palettes, including Hasbro's brand system and Peacock, as the supporting colour. Seen in: Hasbro (https://brandsweets.com/colors/brands/hasbro-com), Peacock (https://brandsweets.com/palettes/vivid#peacock), Linkedin (https://brandsweets.com/colors/brands/linkedin-com). — https://brandsweets.com/colors/denim
- **Teal** #008080 [harmony: split] — Teal is a split-complement of #b51cab: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/teal

- **Blue Violet** #8a2be2 [harmony: analogous] — Blue Violet is #b51cab's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces. — https://brandsweets.com/colors/blueviolet
