Create an abstract background design that features a dynamic interplay of colors, with one side showcasing a vibrant yellow-orange mix and the other side a deep blue. The two colors should appear to be in a visual struggle for dominance, creating a smooth, flowing curve that runs vertically down the center of the image. The matte texture should be subtly visible, enhancing the overall depth. Strong natural sunlight illuminates the scene, casting a realistic 3D shadow that accentuates the curve and adds a sense of energy and movement to the composition.
