Anti-Gravity Inverted Silhouette Cloud Sea Book Cover AI Image Prompt

Around [theme object], generate a calm, anti-gravity-feeling book cover or poster visual: the theme-derived environmental silhouette is inverted as a whole and pressed against the top edge, retaining hard structures, fine pipes, suspended outlines, and a few glowing details at the edges, like the real world turned upside down and attached high above; below, a large area of clean cloud vapor and sky negative space unfolds, with cloud clusters supporting the text through soft volume, misted boundaries, and layered depth, creating a strong contrast between the hard inverted reflection above and the light cloud sea below. Colors are derived from the theme semantics while maintaining the same role relationships: use low-brightness, cool dark tones in the shadows as the top weight, spread high-brightness, low-saturation air colors in the middle, and let warm colors appear only as cloud reflections and edge halos; overall bright, clean, lightly misted, avoiding murky grain and heavy distressing. Main text uses pure white, low-contrast geometric sans-serif, with thin straight strokes, open counters, and loose spacing, arranged in several vertical columns interspersed in front of the clouds; the largest title column occupies the visual center with expanded letter spacing, while smaller credit and subtitle columns sit close to one side to create rhythm; the text does not obscure the inverted silhouette but floats like measurement ticks in misty light. The composition builds the reading path through the top pressure of the inverted entity, the broad buffer of the clouds, and the quiet descent of vertical text; theme content only replaces the inverted silhouette, hinted shapes in the clouds, and text semantics, and must preserve the relationships among flipped world, soft-cloud void, white text columns, cool/warm air separation, and clean digital photography texture. Also make it a sci-fi book cover with a [theme content] theme, suitable for a technology novel or cloud computing topic cover; use [primary color] as the main color, the top inverted silhouette is a whole hanging [inverted object] with bridge pipes, the visual weight presses at the upper center, keep a broad transparent cloud sea below, the title slowly descends from the central axis as thin vertical white text, the subtitle sits near the right side forming a slightly offset rhythm; aspect ratio is vertical 3:4.
