## Colors that go with #660a3a

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 #660a3a'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), M&M's (https://brandsweets.com/colors/brands/mms-com), Burger King (https://brandsweets.com/colors/brands/bk-com), Tim Hortons (https://brandsweets.com/colors/brands/timhortons-com). — https://brandsweets.com/colors/crimson
- **Teal** #008080 [harmony, pool: complementary] — Teal sits directly opposite #660a3a on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight. Seen in: Saffron (https://brandsweets.com/palettes/warm#saffron). — https://brandsweets.com/colors/teal
- **Denim** #1560bd [pool] — Designers have shipped Denim with #660a3a: 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), Box (https://brandsweets.com/colors/brands/box-com). — https://brandsweets.com/colors/denim
- **Forest Green** #228b22 [harmony: split] — Forest Green is a split-complement of #660a3a: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/forestgreen
- **Blue** #0000ff [pool] — Two real palettes: Tim Hortons's brand system and Dunkin''s brand system put Blue beside #660a3a, 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
- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #660a3a: 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
- **Copper** #b87333 [pool] — Designers have shipped Copper with #660a3a: two real palettes: Bramble and Chipotle's brand system, as the supporting colour. Seen in: Bramble (https://brandsweets.com/palettes/muted#bramble), Chipotle (https://brandsweets.com/colors/brands/chipotle-com). — https://brandsweets.com/colors/copper
- **Cream** #fffdd0 [role] — Cream is the surface #660a3a wants: a warm off-white that shares its undertone, so #660a3a reads softer on it than on pure white. — https://brandsweets.com/colors/cream
