画像のプロンプト
Vertical 3:4 minimal graphic print, matte near-black background, a precisely aligned array of12 columns by17 rows of small colored circular disks. Centers run from x5% to95% and y5% to95%, equal row spacing and equal column spacing, no offsets. Each disk diameter about3% of canvas width; large black gaps between circles remain visually dominant. Circles randomly distribute a restrained palette of electric royal blue, softer sky blue, pale periwinkle, light peach, coral pink, and saturated red-orange, with no overall gradient, no repeated rows and no single color forming a symbol. Equal-size flat-filled circles, fine subtly textured paper grain visible both inside disks and background, crisp slightly organic edges without outlines. No light source or shadow, no dimensional depth. Preserve even outer margins and the exact orthogonal geometry.
Negative prompt
No staggered polka dots, no circles touching, no glossy spheres, no drop shadows, no gradients within circles, no bright background, no letters, no hidden symbol, no decorative border.
