## Colors that go with #a540a5

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

- **Sea Green** #2e8b57 [harmony, pool: complementary] — Sea Green sits directly opposite #a540a5 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.

- **Teal** #008080 [harmony, pool: split] — Teal is a split-complement of #a540a5: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. Seen in: Gemstone (https://brandsweets.com/palettes/vivid#gemstone). — https://brandsweets.com/colors/teal
- **Charcoal** #36454f [role, pool] — Charcoal is the text near-black for #a540a5: 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
