App Icon Halloween Design AI Prompt

Edit only the background inside the supplied rounded-square app icon. Preserve every foreground logo pixel exactly: shape, size, position, color, typography, spacing and sharp edges. Never redraw, cover, light, shadow or touch the logo. For each generation, unpredictably choose exactly ONE equally eligible scene below. Order gives no priority; do not default to the first, easiest or previous choice. Render only the chosen row and never mix rows: - Haunted corridor — arches, crooked doors, distant ghost. - Corn maze — tall corn, winding path, scarecrow, moon. - Séance parlor — round table, chairs, crystal ball. - Haunted swamp — twisted willow, boardwalk, moon. - Abandoned nursery — crib, rocking horse, moonlit window. - Ruined chapel — pointed arches, broken pews, rose window. - Catacombs — stone arch, wall niches, iron gate. - Haunted street — leaning houses, crooked lamppost, moon. - Clock tower — huge clock face, gears, staircase. - Mausoleum garden — mausoleum, stone angel, moon. - Haunted greenhouse — broken glass arches, dead vines, ghost. - Harvest yard — scarecrow, unlit pumpkins, fence, barn. - Haunted library — tall shelves, rolling ladder, ghost. - Witch laboratory — cauldron, bottles, arched window. - Gothic ballroom — tall windows, chandelier, empty floor. - Crypt entrance — stone stairs, iron doors, moon. - Haunted attic — roof beams, trunks, round window. - Cemetery gate — iron gate, tombstones, moon. - Abandoned carnival — Ferris-wheel silhouette, striped tent, fog. - Vampire courtyard — gothic fountain, bats, castle arch. - Witch forest — crooked trees, hanging charms, crescent moon. - Underground dungeon — barred cells, chains, end doorway. - Pumpkin field — rows of unlit pumpkins, dead tree, moon. - Haunted train platform — old clock, empty tracks, distant ghost. Flat premium 2D vector scene: large clean silhouettes, subtle tonal gradients, no texture or 3D. Keep the logo dominant, center calm, and one scene anchor clearly readable at 48×48. Palette: black plus tonal shades of the icon's principal color. Preserve white for a white logo; otherwise one small moon/window may be cool near-white. No unrelated hues or warm orange/yellow glow. Add three soft translucent tonal fog layers across the lower 25–30%; never cover the logo. Output an exact 1:1 square: centered complete rounded-square tile at about 82% width and height on pure white, with equal margins. No crop, mockup, outer shadow, pattern, added text or watermark.
