- **Forest Green** #228b22 [harmony: complementary] — Forest Green sits directly opposite #570057 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

- **Charcoal** #36454f [role, pool] — Charcoal is the text near-black for #570057: softer than #000 and cool enough to feel like part of the same palette. Seen in: Hinge (https://brandsweets.com/colors/brands/hinge-co). — https://brandsweets.com/colors/charcoal
