## Colors that go with #efffdc

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

- **Charcoal** #36454f [role, pool] — Charcoal is the body-text near-black for #efffdc: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy. Seen in: Frost & Ember (https://brandsweets.com/palettes/bold#frost-and-ember), Canopy (https://brandsweets.com/palettes/cool#canopy), Tide Pool (https://brandsweets.com/palettes/cool#tide-pool), Paper & Pine (https://brandsweets.com/palettes/minimal#paper-and-pine). — https://brandsweets.com/colors/charcoal
- **Cornflower Blue** #6495ed [harmony, pool: split] — Cornflower Blue is a split-complement of #efffdc: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
