Blue & White Facebook Graphics

I’m refreshing my Facebook presence and need a set of standout visuals that rely solely on a blue-and-white colour palette. This is pure graphic design—no coding or web work—so I’m looking for polished post images (square) plus a matching cover that feel cohesive and on-brand.

Please use modern, clean typography that pairs well with the two colours, and balance negative space so the graphics remain readable once Facebook’s interface elements overlay them. Final files should come layered (PSD or AI) as well as ready-to-upload PNG/JPEG versions. If you have questions about dimensions or style references, let me know; I’m happy to share examples.
