充满活力的颓废主义背景，带有分层的街头海报和温暖的大地色油漆笔触

y textured abstract grunge background built from layers of torn street posters, sun-baked advertising fragments, and dusty paper edges. Broad strokes of warm orange, beige, and soft terracotta blend with splashes of turquoise and hints of blue graffiti, creating a distressed urban collage aesthetic. The composition feels weathered and sun-faded, with peeled textures, scuffed surfaces, and soft shadows suggesting years of exposure on a city wall. Perfect for modern urban design, gritty editorial layouts, and artistic overlays that require a warm yet energetic distressed atmosphere.
