Create a vibrant pop art illustration that captures a bustling city street at night, enveloped in a thick layer of neon-colored fog. The scene should feature stylized buildings adorned with bright neon signs in colors like electric blue, hot pink, and vivid green. The fog should swirl around the streetlights and vehicles, creating a dreamlike atmosphere that softens the sharp edges of the urban landscape. Use bold outlines and halftone patterns to enhance the pop art aesthetic, emphasizing the contrast between the bright colors and the muted tones of the fog. This artwork should evoke a sense of nightlife energy and urban mystique, inviting viewers to immerse themselves in the colorful chaos of a city alive with light and fog.
