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

- **Violet** #ee82ee [harmony: complementary] — Violet sits directly opposite #3bf751 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/violet
- **Deep Sky Blue** #00bfff [pool] — Designers have shipped Deep Sky Blue with #3bf751: 3 real palettes, including Remix's brand system and Prime Video's brand system, as the lead colour.

- **Hot Pink** #ff69b4 [harmony: split] — Hot Pink is a split-complement of #3bf751: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/hotpink

- **Charcoal** #36454f [role] — Charcoal is the body-text near-black for #3bf751: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. — https://brandsweets.com/colors/charcoal
- **Red** #ff0000 [pool] — Red is paired with #3bf751 in two real palettes: Gatorade's brand system and Wise's brand system, as the supporting colour.
