- **Deep Sky Blue** #00bfff [harmony, pool: triadic] — Deep Sky Blue completes a triad with #5def39 — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.

- **Violet** #ee82ee [harmony: complementary] — Violet sits directly opposite #5def39 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 #5def39: 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 #5def39, as the accent.
