## Colors that go with #ff05a3

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

- **Tomato** #ff6347 [harmony, pool: analogous] — Tomato is #ff05a3's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces. Seen in: Night Market (https://brandsweets.com/palettes/vivid#night-market), Airbnb (https://brandsweets.com/colors/brands/airbnb), Sunset Boulevard (https://brandsweets.com/palettes/warm#sunset-boulevard). — https://brandsweets.com/colors/tomato
- **Light Sea Green** #20b2aa [harmony: complementary] — Light Sea Green sits directly opposite #ff05a3 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/lightseagreen
- **Cadet Blue** #5f9ea0 [harmony: split] — Cadet Blue is a split-complement of #ff05a3: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/cadetblue
- **Medium Sea Green** #3cb371 [harmony: split] — Medium Sea Green is a split-complement of #ff05a3: nearly opposite, so it still pops against it, without the vibrating edge of a true complement. — https://brandsweets.com/colors/mediumseagreen
- **Charcoal** #36454f [role] — Charcoal is the body-text near-black for #ff05a3: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. — https://brandsweets.com/colors/charcoal
- **Yellow** #ffff00 [pool] — Two real palettes: JetBrains's brand system and Arcade put Yellow beside #ff05a3, as the accent. Seen in: JetBrains (https://brandsweets.com/colors/brands/jetbrains-com), Arcade (https://brandsweets.com/palettes/vivid#arcade). — https://brandsweets.com/colors/yellow
