Research District Terrain Tilesheet 4x4

Generated from: Pixel art tileset sprite sheet for a 2D side-scrolling platformer, exactly 16 tiles arranged in a strict 4 by 4 grid (4 columns, 4 rows), equal square cells filling the whole image edge to edge, no extra margin, no gridlines, no labels, no separators. Flat front-on orthographic view, no perspective, no drop shadows, crisp chunky pixel clusters, dark outlines, readable when each cell is scaled down to 20x20 pixels. Melancholic urban-decay film-noir palette for a sterile hidden research lab with red alert accents: floor #33363c, wall #23262c, accent #7a2f2f. READ ROW-MAJOR FROM THE TOP-LEFT CELL, in this exact order: row 1: (0) floor_top - pale gray lab floor slab with a lighter clean top edge; (1) floor_fill - repeating pale gray tile floor with thin seams, uniform, fully tileable; (2) platform_top - white lab platform top with a clean pale rim; (3) platform_fill - gray paneled platform underside. row 2: (4) wall - clean sterile panel wall with vertical seams and a thin red accent strip; (5) ceiling - white recessed panel ceiling with a grid of seams; (6) ledge - white lab ledge with a red emergency glow along its face; (7) crate - a white lab equipment container with dark trim. row 3: (8) pipe_h - brushed steel pipe running horizontally with clean couplings; (9) pipe_v - brushed steel pipe running vertically with a sealed junction; (10) sign - a red alert indicator panel made only of abstract glowing bars and rectangles; (11) vent - a clean steel louver vent. row 4: (12) sky - deep near-black interior backdrop with a cold gray glow; (13) silhouette_a - distant lab and industrial complex building silhouettes, flat dark shapes; (14) silhouette_b - closer darker piping and antenna silhouettes; (15) void - flat near-black fill. Seamless tiling: cells 0 through 6 are repeated across the level, so their edges must match up seamlessly with no unique shadow, gradient or vignette. Absolutely NO letters, numbers, words or readable text characters anywhere - evoke signage with abstract glowing shapes only. Keep all colors inside the listed sterile gray and red alert family.
