## Colors that go with #631d4e

Named partners (harmony on the OKLCH wheel, co-occurrence in curated palettes and brand systems, and the neutrals that carry it), best first:

- **Crimson** #dc143c [harmony, pool: analogous] — Crimson is #631d4e'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), Burger King (https://brandsweets.com/colors/brands/bk-com), M&M's (https://brandsweets.com/colors/brands/mms-com), Tim Hortons (https://brandsweets.com/colors/brands/timhortons-com). — https://brandsweets.com/colors/crimson
- **Sea Green** #2e8b57 [harmony: complementary] — Sea Green sits directly opposite #631d4e 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 #631d4e wants: a warm off-white that shares its undertone, so #631d4e reads softer on it than on pure white. Seen in: MetaMask (https://brandsweets.com/colors/brands/metamask-io). — https://brandsweets.com/colors/cream
- **Powder Blue** #b0e0e6 [pool] — Designers have shipped Powder Blue with #631d4e: 3 real palettes, including Macaron and Nursery, as the supporting colour. Seen in: Macaron (https://brandsweets.com/palettes/light#macaron), Nursery (https://brandsweets.com/palettes/light#nursery), Stone (https://brandsweets.com/palettes/neutral#stone). — https://brandsweets.com/colors/powderblue
- **Teal** #008080 [harmony: split] — Teal is a split-complement of #631d4e: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/teal
- **Blue** #0000ff [pool] — Two real palettes: Tim Hortons's brand system and Dunkin''s brand system put Blue beside #631d4e, as the accent. Seen in: Tim Hortons (https://brandsweets.com/colors/brands/timhortons-com), Dunkin' (https://brandsweets.com/colors/brands/dunkindonuts-com). — https://brandsweets.com/colors/blue
- **Blush Pink** #e8b4b8 [pool] — Two real palettes: Nursery and Blush put Blush Pink beside #631d4e, as the lead colour. Seen in: Nursery (https://brandsweets.com/palettes/light#nursery), Blush (https://brandsweets.com/palettes/light#blush). — https://brandsweets.com/colors/blush-pink
- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #631d4e: 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
