Minimalistic Background Templates Set

I need three high-resolution PNG backgrounds—one in crisp white, one in deep charcoal, and one in a rich mid-tone blue. All three should share the same minimalistic design language while still feeling energetic and dynamic rather than flat or sterile. No text, icons, or branding overlays—just versatile backdrops that can drop straight into future layouts.

Please keep any geometric accents, gradients, or subtle textures understated so the colour itself remains the focus. Final files should arrive export-ready (preferably 3000 px wide or larger) and free of compression artefacts. Supplying layered source files is a plus if you build them in tools like Photoshop, Illustrator, or Figma, but the required handoff is three separate, lossless PNGs named clearly by colour.

Let me know your proposed resolution and any questions about style before you begin. Once approved, a quick turnaround is ideal; I only need the finished images—no mock-ups or additional assets.
