Downtown Neon Tileset Atlas 12x12

Generated from: RAW PIXEL-ART TILESET SHEET (sprite atlas), flat front-on view, no perspective. This is a technical tile atlas, NOT a scene, mockup, screenshot, poster or labelled chart - do not draw a landscape, a street panorama, characters, or any frame around the sheet. CANVAS: one perfectly square image divided into a strict 12 by 12 grid of 144 equal square cells. No borders, no gutters, no grid lines, no cell labels, no numbers, no text anywhere. LAYOUT: Only the top two rows contain artwork. Row 1 (top row): all twelve cells, left to right, in the exact order listed below. Row 2: only the leftmost four cells; its remaining eight cells are empty flat fill. Rows 3 through 12: completely empty flat fill. Every non-art cell must be one single flat solid color, deep indigo near-black #0d0b16, totally featureless - no texture, no glow, no gradient, no noise. PIXEL ART RULES: chunky hard-edged pixel art built from large 4x4 pixel blocks, crisp single-color pixels, everything snapped to the grid. No anti-aliasing, no blur, no soft gradients, no drop shadows, no photographic texture. Neon reads as hard bright pixel lines and stepped pixel glow, never a soft airbrushed halo. Nine of the tiles must tile seamlessly: left edge lines up exactly with right edge and top edge with bottom edge, no seam. PALETTE: base deep indigo near-black #0d0b16 and #1a1524; neon magenta #ff2fb0; cyan #35e6ff; violet #8a4dff; warm amber #ffb05a; brick #3a2320 and #241a1a; wet asphalt #16141d. Dark melancholic film-noir cyberpunk. ROW 1, LEFT TO RIGHT, EXACTLY THESE TWELVE TILES: 1. floor_top - walkable street surface: top few pixel rows are a bright neon-reflecting rim (cyan and magenta), on a thin pale curb line, below it dark wet asphalt with faint vertical neon smears. Tiles left-right. 2. floor_fill - dense wet asphalt body: near-black wet pavement, long faint thin vertical magenta/cyan/violet reflection streaks, a couple of darker patch seams, a hairline curb line. Tiles left-right and top-bottom. 3. platform_top - raised sidewalk curb / steel walkway top: bright concrete lip with a thin cyan neon under-light strip and a small magenta hazard chevron trim, damp concrete below. Tiles left-right. 4. platform_fill - dark damp concrete underside with grime stains, a bolt row and a faint drip streak. Tiles left-right and top-bottom. 5. wall - brick storefront facade, side-on: dark red-brown and charcoal brick courses with visible mortar lines, lower half holds a doorway spilling warm amber light plus a closed metal roller shutter, a small magenta neon sign box above the door with abstract glyph shapes, a vertical drainpipe at the right side. Tiles left-right. 6. ceiling - dark concrete soffit / awning underside: a steel pipe and a conduit crossing it edge to edge, faint damp stains. Tiles left-right. 7. ledge - brick and concrete parapet edge: brick courses and a pale concrete cap, cyan neon under-glow along the bottom. Tiles left-right. 8. decor crate - stack of two dark wooden street crates with metal banding and a small magenta neon sticker with an abstract glyph. 9. decor pipe_h - horizontal rusty metal pipe segment with flanges entering at the left edge and leaving at the right edge at the same height, so copies join seamlessly side by side. Tiles left-right. 10. decor pipe_v - vertical rusty metal pipe segment with a valve collar entering at the top edge and leaving at the bottom edge at the same x position, so copies join seamlessly top to bottom. Tiles top-bottom. 11. decor sign - tall vertical neon sign box: dark metal casing, magenta border, three stacked abstract glowing glyph shapes (invented shapes only - NOT letters, NOT kanji, NOT any readable character), cyan inner glow. 12. decor vent - cyan-lit vending machine / utility cabinet: dark metal front, glowing cyan panel, rows of small slots, thin panel lines, a small amber indicator. No text, no numbers. ROW 2, LEFT FOUR CELLS ONLY: 13. background sky - deep indigo night sky, nearly flat, only very subtle horizontal banding in two close indigo tones. 14. background silhouette_a - far city skyline band, very low contrast: dark violet blocky far buildings along the bottom edge, mostly flat. 15. background silhouette_b - nearer, darker skyline: pitch-dark blocky building silhouettes with a few tiny 1-2 pixel lit windows in amber and cyan. 16. background void - near-black, almost featureless, one very dark indigo tone with the faintest texture. No letters, words, numerals, kanji, kana or any readable character anywhere in the image - use only abstract glowing glyph-like neon shapes. No watermark, no signature, no logo.
