- **Olive Green** #808000 [harmony: complementary] — Olive Green sits directly opposite #690dbf 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

- **Royal Blue** #4169e1 [harmony, pool: analogous] — Royal Blue is #690dbf's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.

- **Forest Green** #228b22 [harmony: split] — Forest Green is a split-complement of #690dbf: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/forestgreen
