3D icon of a half-open glass cube with iridescent, holographic colors - the cube is hollow and transparent, with smooth outer edges where a highlighting gradient fades from pink to purple and blue. The interior of the cube reflects gradations of subtle pastel colors from these gradients. The cube material appears almost liquid, having a realistic gloss and a fully transparent pane on one side. The edges and corners are softly rounded, even on the seemingly glass material. The cube is shown slightly tilted to show the inside and outer surfaces, set against a white background, centered, no shadow, clean icon style, high detail, 3D render.
