- **Violet** #ee82ee [harmony: complementary] — Violet sits directly opposite #3ef94e 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

- **Charcoal** #36454f [role] — Charcoal is the body-text near-black for #3ef94e: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. — https://brandsweets.com/colors/charcoal
