## Colors that go with Copper

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

- **Cadet Blue** #5f9ea0 [harmony, pool: split] — Cadet Blue is a split-complement of Copper: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. Seen in: Dusk (https://brandsweets.com/palettes/cool#dusk), Clean Beauty (https://brandsweets.com/palettes/minimal#clean-beauty), Estate (https://brandsweets.com/palettes/luxury#estate), Paper & Pine (https://brandsweets.com/palettes/minimal#paper-and-pine). — https://brandsweets.com/colors/cadetblue
- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for Copper: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. Seen in: Puma (https://brandsweets.com/colors/brands/puma-com), Paper & Pine (https://brandsweets.com/palettes/minimal#paper-and-pine), Harbour (https://brandsweets.com/palettes/cool#harbour), Hermès (https://brandsweets.com/colors/brands/hermes-com). — https://brandsweets.com/colors/charcoal
- **Steel Blue** #4682b4 [harmony, pool: complementary] — Steel Blue sits directly opposite Copper on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
