How to use this prompt

Enumerating exactly four icons and pinning them to "a 2x2 grid" is what keeps DALL·E from improvising a fifth icon or drifting into a loose collage — it treats the list as a checklist and the grid as a layout contract. "Puffy and pillowy with a smooth matte plastic surface" is the material combination to preserve; swap "matte" for "glossy" and the set becomes candy-like, which fights readability at small sizes. "Consistent soft top-left lighting" is the phrase that makes four separate objects feel like one designed family. Extend the pack conversationally — "add a settings gear and a calendar in the same style" — rather than rerunning, because a fresh run rerolls the palette.

Variations to try

  • Swap the theme — "a shopping bag, a credit card, a gift box, and a price tag" reuses the grid for an e-commerce set
  • Dark mode pass — "the same four icons on a deep navy background, icons in muted neon pastels, slightly stronger rim light"
