Navy Sinking Into Coral, a Sky Gradient Wallpaper

A horizontal 16:9 wallpaper that is nothing but a pure gradient sky, with no objects or foreground elements. Keep the center-left area intentionally empty to preserve negative space, so overlays stay legible. The colour moves in one smooth diagonal sweep: deep navy at the upper left, warm coral at the lower right, with a faint mid-tone band across the lower third that only hints at a horizon. Cooler blue-teal undertones sit high in the sky and melt into peach-amber warmth below, as if soft atmospheric scattering were adding depth. Edges stay soft and continuous, free of banding and hard seams, and any micro grain or noise stays below 2% so the image holds up in print and on screen. Add a gentle, wide vignette that darkens the outer 10% of the frame, framing the center without a visible rim line. Deliver the final composition cropped to an exact 16:9 aspect ratio at the intended resolution, with the gradient centered and no added elements or text.
