Composed for a 9:16 vertical wallpaper, create a deep crimson underglow rising from the lower third into near-black at the top, like light passing through thin atmospheric haze. Anchor the brightest red low and slightly off-center, then let it fade through charcoal-red midtones into a clean dark upper field. The top third stays calm and darker for breathing room, with a soft vignette that keeps edges OLED-friendly.
Add premium texture that stays subtle: faint grain, pigment-like clouding, and a gentle haze layer that makes the gradient feel dimensional. Keep transitions ultra-smooth with no visible steps or harsh bands, and keep the red intensity restrained and refined. The surface should read like a photographed backdrop plate, not a flat graphic.
Reserve a clean negative-space zone in the upper half where the gradient is darkest and most uniform. Maintain a minimal, unmarked field with no distinct forms, so the wallpaper stays versatile. The overall look should feel expensive, cinematic, and quiet.
