Generation prompt
This is the submitted prompt. It can guide a similar image; it does not reproduce identical pixels or establish native dimensions.
Use case: stylized-concept. Asset type: a downloadable abstract background for screens, websites and presentations. Create exactly one finished image, widescreen 16:9, requesting native 3840×2160 pixels when available. An expansive midnight-blue color field with one broad soft vertical plume of cobalt and powder-blue light drifting upward near the center-right. Its edges dissolve naturally into the surrounding dark field; subtle darker overlapping haze adds depth. Left third stays calm and dark for pale text. Make this a diffused pigment-light atmosphere, not glass or flowing ribbons. Gentle organic grain, no stars, neon, clouds, literal smoke or recognizable objects. Palette: #111e36, #315b83, #8cabc2. Edge-to-edge composition. Preserve useful centered 16:9, 16:10, MacBook, phone and ultrawide crops. No text, lettering, logos, watermark, border, people, tiny clutter, banding, compression artifacts or unwanted recognizable objects.
