## Colors that go with #cd21e8

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

- **Forest Green** #228b22 [harmony: complementary] — Forest Green sits directly opposite #cd21e8 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/forestgreen
- **Charcoal** #36454f [role, pool] — Charcoal is the text near-black for #cd21e8: softer than #000 and cool enough to feel like part of the same palette. Seen in: Hasbro (https://brandsweets.com/colors/brands/hasbro-com). — https://brandsweets.com/colors/charcoal
- **Dark Cyan** #008b8b [harmony, pool: triadic] — Dark Cyan completes a triad with #cd21e8 — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash. Seen in: Peacock (https://brandsweets.com/palettes/vivid#peacock). — https://brandsweets.com/colors/darkcyan
- **Olive Green** #808000 [harmony: split] — Olive Green is a split-complement of #cd21e8: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/olive
