- **Forest Green** #228b22 [harmony: complementary] — Forest Green sits directly opposite #640665 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
- **Denim** #1560bd [pool] — Designers have shipped Denim with #640665: 3 real palettes, including Hinge's brand system and Slack's brand system, as the accent.

- **Charcoal** #36454f [role, pool] — Charcoal is the text near-black for #640665: 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
