"Create an image that features a distinct contrast between its two halves. On the left side, fill the area with vibrant and varied colors, showcasing a spectrum of hues that blend and transition smoothly across the space. This side should exude energy and liveliness through its colorful display. On the right side, the image transitions to pure black, symbolizing stark contrast. This half should embody stillness and the absence of color, creating a powerful visual dichotomy. The boundary between the two halves should be clear but not harsh, allowing for a slight gradient where the colors fade into black, emphasizing the contrast between vibrancy and void.high resolution, UHD, 8K, Ultra High Definition, High Quality, 32K, HDR, --ar 16:9
