## Colors that go with #640c5e

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 #640c5e 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 #640c5e wants: a warm off-white that shares its undertone, so #640c5e 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 #640c5e: 3 real palettes, including Hinge's brand system and Slack's brand system, as the accent. Seen in: Hinge (https://brandsweets.com/colors/brands/hinge-co), Slack (https://brandsweets.com/colors/brands/slack-com), Heinz (https://brandsweets.com/colors/brands/heinz-com). — https://brandsweets.com/colors/denim
- **Teal** #008080 [harmony: split] — Teal is a split-complement of #640c5e: 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 #640c5e: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/olive
- **Blue Violet** #8a2be2 [harmony, pool: analogous] — Blue Violet is #640c5e's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces. Seen in: Taco Bell (https://brandsweets.com/colors/brands/tacobell-com). — https://brandsweets.com/colors/blueviolet
- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #640c5e: 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
- **Tomato** #ff6347 [pool] — Two real palettes: Golden Hour and FedEx's brand system put Tomato beside #640c5e, as the supporting colour. Seen in: Golden Hour (https://brandsweets.com/palettes/warm#golden-hour), FedEx (https://brandsweets.com/colors/brands/fedex-com). — https://brandsweets.com/colors/tomato
