- **Royal Blue** #4169e1 [harmony, pool: analogous] — Royal Blue is #a135f3's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.

- **Olive Drab** #6b8e23 [harmony: complementary] — Olive Drab sits directly opposite #a135f3 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/olivedrab
- **Sea Green** #2e8b57 [harmony, pool: split] — Sea Green is a split-complement of #a135f3: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. Seen in: Next.js (https://brandsweets.com/colors/brands/nextjs-org). — https://brandsweets.com/colors/seagreen
