How to use this prompt

The indigo-and-gold split is the design decision: "luminous gold core" against "sweeping indigo spiral arms" gives the image one warm focal point instead of the uniform blue-white soup SDXL defaults to for galaxies. "Deep black space at the frame corners" is what makes this work as a desktop — icons and the taskbar land on true black instead of starfield noise. The negative "nebula clouds filling the frame" is load-bearing; without it SDXL pads 16:9 with gas and the galaxy loses its silhouette. If the core blows out to white, lower cfg to 6 rather than editing the prompt — it is a guidance artifact, not a wording problem.

Variations to try

  • Edge-on version — swap the composition for "galaxy viewed edge-on, thin luminous disc with a dark dust lane splitting it horizontally" for a subtler wallpaper
  • Twin version — add "a small companion dwarf galaxy glowing faintly in the lower right corner" to fill an ultrawide 21:9 rerun
