Design a pop art piece that depicts an urban jungle shrouded in colorful fog. The composition should feature a bustling city street filled with stylized buildings, trees, and vibrant street art, all rendered in bold, saturated colors like lime green, fiery orange, and cobalt blue. The fog should be represented with swirling patterns of translucent hues that blend seamlessly with the urban elements, creating a sense of depth and movement. Use thick black outlines to define the shapes of the buildings and foliage, enhancing the graphic quality of the artwork. This piece should convey a lively, energetic atmosphere, inviting viewers to experience the vibrant chaos of a city enveloped in a colorful mist.
