- **Dark Orchid** #9932cc [harmony: complementary] — Dark Orchid sits directly opposite #00510a 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/darkorchid
- **Teal** #008080 [harmony, pool: analogous] — Teal is #00510a's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces. Seen in: N26 (https://brandsweets.com/colors/brands/n26-com), Gusto (https://brandsweets.com/colors/brands/gusto-com). — https://brandsweets.com/colors/teal

- **Medium Violet Red** #c71585 [harmony: split] — Medium Violet Red is a split-complement of #00510a: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/mediumvioletred
- **Cream** #fffdd0 [role] — Cream is the surface #00510a wants: a warm off-white that shares its undertone, so #00510a reads softer on it than on pure white. — https://brandsweets.com/colors/cream
