blue background gradient smooth
Prompt
Create a clean, smooth abstract background with a soft radial gradient: a luminous pale yellow glow centered slightly below the exact middle, blending outward into muted yellow-green, then gentle aqua, and finally calm medium sky blue at all four edges. The surface should feel seamless, matte, and evenly diffused like a softly lit studio backdrop with no texture, objects, horizon line, or visible pattern. Mood is fresh, airy, optimistic, and minimal, with a commercial stock background aesthetic. Compose as a square frame, perfectly centered and balanced, with subtle falloff and ultra-smooth transitions, as if photographed on a macro lens at f/8 with completely defocused light.
