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 #a11abc: 4 real palettes, including Peacock and Hasbro's brand system, as the supporting colour. Seen in: Peacock (https://brandsweets.com/palettes/vivid#peacock), Hasbro (https://brandsweets.com/colors/brands/hasbro-com), Linkedin (https://brandsweets.com/colors/brands/linkedin-com), Slack (https://brandsweets.com/colors/brands/slack-com). — https://brandsweets.com/colors/denim
- **Forest Green** #228b22 [harmony: complementary] — Forest Green sits directly opposite #a11abc 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/forestgreen
- **Sea Green** #2e8b57 [harmony, pool: split] — Sea Green is a split-complement of #a11abc: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. Seen in: Next.js (https://brandsweets.com/colors/brands/nextjs-org). — https://brandsweets.com/colors/seagreen
- **Charcoal** #36454f [role, pool] — Charcoal is the text near-black for #a11abc: softer than #000 and cool enough to feel like part of the same palette. Seen in: Hasbro (https://brandsweets.com/colors/brands/hasbro-com). — https://brandsweets.com/colors/charcoal
- **Teal** #008080 [harmony, pool: triadic] — Teal completes a triad with #a11abc — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash. Seen in: Gemstone (https://brandsweets.com/palettes/vivid#gemstone). — https://brandsweets.com/colors/teal
- **Olive Green** #808000 [harmony: split] — Olive Green is a split-complement of #a11abc: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/olive

Seen in: Taco Bell (https://brandsweets.com/colors/brands/tacobell-com), Circuit (https://brandsweets.com/palettes/technical#circuit). — https://brandsweets.com/colors/lightseagreen
- **Medium Violet Red** #c71585 [harmony: analogous] — Medium Violet Red is #a11abc'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/mediumvioletred
