- **Sea Green** #2e8b57 [harmony: complementary] — Sea Green sits directly opposite #ac1591 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
- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #ac1591: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. Seen in: Hasbro (https://brandsweets.com/colors/brands/hasbro-com). — https://brandsweets.com/colors/charcoal
- **Crimson** #dc143c [harmony, pool: analogous] — Crimson is #ac1591's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
