- **Forest Green** #228b22 [harmony: complementary] — Forest Green sits directly opposite #b31eb3 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/forestgreen
- **Teal** #008080 [harmony, pool: split] — Teal is a split-complement of #b31eb3: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. Seen in: Gemstone (https://brandsweets.com/palettes/vivid#gemstone). — https://brandsweets.com/colors/teal
- **Charcoal** #36454f [role, pool] — Charcoal is the text near-black for #b31eb3: softer than #000 and cool enough to feel like part of the same palette. Seen in: Hasbro (https://brandsweets.com/colors/brands/hasbro-com). — https://brandsweets.com/colors/charcoal
