Create a vibrant abstract oum4bstract composition featuring a series of concentric circles, each with distinct color gradients, centered within the frame, showcasing a harmonious blend of hues. The background is a soft, off-white hue, providing a neutral canvas for the colorful circular elements to pop, while the atmosphere is one of serenity and balance. The artwork employs a minimalist, geometric style reminiscent of mid-century modern design, with clean lines and flat, blended color fields; the color palette is carefully considered, with warm oranges, yellows, and reds transitioning smoothly into cooler teals, blues, and pinks. The composition is a symmetrical, close-up shot, emphasizing the circular forms, and the rendering quality should be high, with a slightly textured, watercolor-like finish, giving the image a tactile feel; incorporate subtle gradients and soft edges where the colors meet, with no sharp lines, and add a very slight grainy texture to enhance the artistic style.
