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

- **Teal** #008080 [harmony, pool: complementary] — Teal sits directly opposite darkred on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.

- **Crimson** #dc143c [pool] — Crimson is paired with darkred in 4 real palettes, including State Farm's brand system and Wendy's's brand system, as the lead colour.

- **Steel Blue** #4682b4 [harmony, pool: split] — Steel Blue is a split-complement of darkred: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. Seen in: Wendy's (https://brandsweets.com/colors/brands/wendys-com). — https://brandsweets.com/colors/steelblue
- **Champagne** #f7e7ce [pool] — 3 real palettes, including Bramble and Woodsmoke put Champagne beside darkred, as the text colour against it.

- **Royal Blue** #4169e1 [harmony, pool: triadic] — Royal Blue completes a triad with darkred — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash. Seen in: Bose (https://brandsweets.com/colors/brands/bose-com). — https://brandsweets.com/colors/royalblue
- **Cream** #fffdd0 [role] — Cream is the surface darkred wants: a warm off-white that shares its undertone, so darkred reads softer on it than on pure white. — https://brandsweets.com/colors/cream
