- **Sea Green** #2e8b57 [harmony: complementary] — Sea Green sits directly opposite #57003b 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
- **Cream** #fffdd0 [role, pool] — Cream is the surface #57003b wants: a warm off-white that shares its undertone, so #57003b reads softer on it than on pure white. Seen in: MetaMask (https://brandsweets.com/colors/brands/metamask-io). — https://brandsweets.com/colors/cream
