Envision a contemporary sneaker, named the Lomello 2. This unique piece of footwear should embody the vibe of space holograms. The design should incorporate colors and aesthetics often associated with the cosmos and holography, including shimmering blues, purples, and silvers. The sneaker might include elements representative of stars, galaxies, and nebulas, all with a holographic twist. Please ensure there is absolutely no text in the image.
