- **Violet** #ee82ee [harmony: complementary] — Violet sits directly opposite #5df40b 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
- **Hot Pink** #ff69b4 [harmony: split] — Hot Pink is a split-complement of #5df40b: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/hotpink
- **Blue** #0000ff [pool] — Two real palettes: MongoDB's brand system and Robinhood's brand system put Blue beside #5df40b, as the accent.

- **Charcoal** #36454f [role] — Charcoal is the body-text near-black for #5df40b: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. — https://brandsweets.com/colors/charcoal
- **Lilac** #c8a2c8 [harmony: split] — Lilac is a split-complement of #5df40b: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/lilac
