## Colors that go with #39f500

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 #39f500 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 [harmony, pool: triadic] — Deep Sky Blue completes a triad with #39f500 — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash. Seen in: Remix (https://brandsweets.com/colors/brands/remix-run), Learning App (https://brandsweets.com/palettes/playful#learning-app). — https://brandsweets.com/colors/deepskyblue
- **Hot Pink** #ff69b4 [harmony: split] — Hot Pink is a split-complement of #39f500: 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 #39f500: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. — https://brandsweets.com/colors/charcoal
