How to use this prompt
"Matte gradient sphere" is the phrase that holds the whole cover — say "ball" and SDXL renders a glossy 3D object; "matte" plus "gradient" keeps it flat and atmospheric, which is the ambient-mood brief. A single object is non-negotiable; the negative prompt's "multiple objects" ban stops SDXL from scattering decorative stars around it. The slate-blue and sand pairing is deliberately desaturated so the cover reads calm rather than cinematic. "Analogue film grain" adds the texture that prevents the gradient from looking like a CSS backdrop. The blank lower band is the title slot; ambient sleeves use tiny lowercase type, so leave the space and set the word afterwards.
Variations to try
- Recolour the sphere to deep rust and pale ivory for a warmer drone palette
- Split the sphere into two overlapping moons for a duotone celestial concept
