- **Sea Green** #2e8b57 [harmony: complementary] — Sea Green sits directly opposite #640261 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/seagreen
- **Denim** #1560bd [pool] — Designers have shipped Denim with #640261: 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 #640261: 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
- **Tomato** #ff6347 [pool] — Two real palettes: FedEx's brand system and Golden Hour put Tomato beside #640261, as the supporting colour.

- **White Smoke** #f5f5f5 [role] — White Smoke is the surface for #640261: a clean near-white with no warm cast, so the cool hue stays clear instead of drifting muddy. — https://brandsweets.com/colors/whitesmoke
