Create a pop art digital painting that showcases a vibrant cityscape enveloped in colorful fog. The scene should feature bold, saturated colors like electric pinks, bright yellows, and deep blues, contrasting sharply with the soft, swirling fog. Use graphic outlines to define the shapes of buildings and street elements, creating a dynamic composition that draws the viewer's eye. Incorporate playful patterns within the fog, suggesting movement and energy, while maintaining a sense of urban mystique. This piece should evoke a lively yet dreamy atmosphere, inviting viewers to explore the intersection of bold art and atmospheric beauty.
