- **Crimson** #dc143c [harmony, pool: analogous] — Crimson is #641645's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.

- **Sea Green** #2e8b57 [harmony: complementary] — Sea Green sits directly opposite #641645 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
- **Teal** #008080 [harmony, pool: split] — Teal is a split-complement of #641645: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. Seen in: Saffron (https://brandsweets.com/palettes/warm#saffron). — https://brandsweets.com/colors/teal
- **Cream** #fffdd0 [role, pool] — Cream is the surface #641645 wants: a warm off-white that shares its undertone, so #641645 reads softer on it than on pure white. Seen in: MetaMask (https://brandsweets.com/colors/brands/metamask-io). — https://brandsweets.com/colors/cream
