- **Violet** #ee82ee [harmony: complementary] — Violet sits directly opposite #42f207 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 #42f207: 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 #42f207: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. — https://brandsweets.com/colors/charcoal
