## Colors that go with #670451

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 #670451 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 #670451 wants: a warm off-white that shares its undertone, so #670451 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 #670451: 3 real palettes, including Hinge's brand system and Heinz's brand system, as the accent. Seen in: Hinge (https://brandsweets.com/colors/brands/hinge-co), Heinz (https://brandsweets.com/colors/brands/heinz-com), Slack (https://brandsweets.com/colors/brands/slack-com). — https://brandsweets.com/colors/denim
- **Teal** #008080 [harmony: split] — Teal is a split-complement of #670451: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/teal
- **Forest Green** #228b22 [harmony: split] — Forest Green is a split-complement of #670451: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/forestgreen
- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #670451: 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 [harmony, pool: analogous] — Crimson is #670451's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces. Seen in: Lenovo (https://brandsweets.com/colors/brands/lenovo-com). — https://brandsweets.com/colors/crimson
- **Olive Green** #808000 [harmony: triadic] — Olive Green completes a triad with #670451 — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash. — https://brandsweets.com/colors/olive
