## Fuller red variant generation prompt

Use case: stylized-concept. Create an elegant abstract background for an art auction editorial website, landscape 16:9. Matte charcoal slate base with sculptural flowing layered ribbons and gently folded planes. Fuller composition with MORE rich muted wine red, brick red and deep ArtSpotter crimson than a minimal charcoal wallpaper, but restrained and sophisticated, no neon or orange. Place multiple generous curving red and charcoal layers along BOTH left and right sides, extending through the upper outer corners and lower outer corners, framing a quiet central vertical column. Critical composition: central 42 percent of image width, from top to bottom, must stay calm dark neutral charcoal, with absolutely no red or bright shapes behind the centered login card; red forms must remain in the outer 29 percent on each side. Soft diffuse lighting, matte paper/satin finish, subtle depth, softly curved diagonal movement and balanced asymmetry. The outer edges should feel richly composed and visibly red, not empty; center calm and uncluttered. No vivid highlights, sharp metallic spikes, gaming style or heavy texture. Background asset only, no login card, no UI, no text, no logo, no watermark, no border. High-quality contemporary gallery aesthetic.

## Subtle variant generation prompt

Use case: stylized-concept. Generate a new refined abstract background for an art auction editorial website, wide landscape 16:9. This is a subtle alternative to a charcoal background with dramatic diagonal red metallic ribbons: make it distinctly calmer and a little lighter. Soft matte slate charcoal gray (#30343d), generous quiet negative space across the middle 60 percent for a centered white login card, and a dark enough upper center for a white wordmark. At the far right and bottom left edges, barely visible large layered curved paper-like planes with soft diffuse shadows, gentle flowing diagonal direction, only a whisper of muted deep burgundy red at the extreme edges. Restrained contemporary art gallery stationery aesthetic, understated and elegant. Smooth matte surfaces, subtle tonal variation, no bright highlights, no sharp metallic blades, no bright red stripes, no heavy black, no busy geometry. Background only: no text, no logos, no UI, no card, no border, no watermark. The primary impression should be quiet charcoal with very subtle red warmth, not a gaming wallpaper.

## Generation prompt

Use case: stylized-concept. Create a polished abstract website background image for ArtSpotter, an art auction editorial application. Wide landscape 16:9, preferably 1920x1080. Dark charcoal graphite base (#252936), with just a few generous architectural folded planes and sweeping diagonal beveled ribbons in rich oxblood and muted ArtSpotter red (#b01917), moving from bottom left toward upper right. Restrained contemporary gallery / premium design studio aesthetic, matte surfaces with subtle satin edge lighting, gentle depth, beautifully controlled tonal gradients. Most accents should be at the right edge and lower left corner; keep the middle 40 percent and upper middle quiet dark charcoal because a centered white login card and a white wordmark will be overlaid there. Overall calmer, more spacious and sophisticated than a busy red angular gaming wallpaper. Background asset ONLY, edge to edge. No text, no lettering, no logo, no UI, no form, no border, no watermark, no orange, no pink neon, no purple, no clutter.
