Abstract expressionist painting dominated by shades of gray, white, and vibrant blue. Use bold, vertical brushstrokes to create a textured, layered effect. The composition should feature a large central area of intense blue, surrounded by various tones of gray and white. Incorporate drips, splatters, and rough edges to give a sense of spontaneity and raw emotion. Some areas should appear scratched or scraped, revealing underlying layers. The overall effect should be dynamic and chaotic, with a strong contrast between the cool blue and the neutral grays. The style should evoke a sense of urban decay or a turbulent sky
