## Colors that go with #51004e

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 #51004e 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
- **Cream** #fffdd0 [role, pool] — Cream is the surface #51004e wants: a warm off-white that shares its undertone, so #51004e reads softer on it than on pure white. Seen in: MetaMask (https://brandsweets.com/colors/brands/metamask-io). — https://brandsweets.com/colors/cream
- **Denim** #1560bd [pool] — Designers have shipped Denim with #51004e: 3 real palettes, including Heinz's brand system and Hinge's brand system, as the accent. Seen in: Heinz (https://brandsweets.com/colors/brands/heinz-com), Hinge (https://brandsweets.com/colors/brands/hinge-co), Discover (https://brandsweets.com/colors/brands/discover-com). — https://brandsweets.com/colors/denim
- **Teal** #008080 [harmony: split] — Teal is a split-complement of #51004e: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/teal
- **Olive Green** #808000 [harmony: split] — Olive Green is a split-complement of #51004e: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/olive

- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #51004e: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. Seen in: Hinge (https://brandsweets.com/colors/brands/hinge-co). — https://brandsweets.com/colors/charcoal
- **Crimson** #dc143c [pool] — Crimson is paired with #51004e in two real palettes: Lenovo's brand system and Tim Hortons's brand system, as the supporting colour.
