- **Royal Blue** #4169e1 [harmony, pool: analogous] — Royal Blue is #9637fb's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.

- **Olive Green** #808000 [harmony: complementary] — Olive Green sits directly opposite #9637fb 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/olive
- **Charcoal** #36454f [role, pool] — Charcoal is the text near-black for #9637fb: softer than #000 and cool enough to feel like part of the same palette. Seen in: Hasbro (https://brandsweets.com/colors/brands/hasbro-com). — https://brandsweets.com/colors/charcoal
- **Sea Green** #2e8b57 [harmony: split] — Sea Green is a split-complement of #9637fb: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/seagreen
