Glass ball with rainbow gradient

A glowing sphere floats against a dark background, exhibiting a smooth gradient of blue, purple, cyan, and yellow hues. The sphere appears illuminated from within, creating a radiant, almost neon effect that softly blends colors along its curved surface. Subtle shadows and light streaks emphasize the spherical form, producing a futuristic and abstract visual impression. The dark backdrop enhances the vibrant and luminous qualities of the sphere, making it the focal point of the composition. This abstract design conveys motion and fluidity through its seamless color transitions and glowing appearance.
