## Colors that go with #c91fef

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

- **Olive Drab** #6b8e23 [harmony: complementary] — Olive Drab sits directly opposite #c91fef 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/olivedrab
- **Charcoal** #36454f [role, pool] — Charcoal is the text near-black for #c91fef: 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 #c91fef — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
