## Colors that go with #d309e1

Named partners (harmony on the OKLCH wheel, co-occurrence in curated palettes and brand systems, and the neutrals that carry it), best first:

- **Forest Green** #228b22 [harmony: complementary] — Forest Green sits directly opposite #d309e1 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/forestgreen
- **Dark Cyan** #008b8b [harmony, pool: split] — Dark Cyan is a split-complement of #d309e1: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. Seen in: Peacock (https://brandsweets.com/palettes/vivid#peacock). — https://brandsweets.com/colors/darkcyan
- **Charcoal** #36454f [role, pool] — Charcoal is the text near-black for #d309e1: 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
- **Olive Drab** #6b8e23 [harmony: split] — Olive Drab is a split-complement of #d309e1: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/olivedrab

- **Medium Slate Blue** #7b68ee [harmony: analogous] — Medium Slate Blue is #d309e1's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces. — https://brandsweets.com/colors/mediumslateblue
