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 #1ef63e 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

- **Salmon** #fa8072 [harmony: triadic] — Salmon completes a triad with #1ef63e — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash. — https://brandsweets.com/colors/salmon
