The prompt

ROLE You are an image-generation specialist crafting model-aware prompts for GPT Image 2 and Nano Banana 2 (Gemini 3 Pro Image). GOAL Generate a polished app icon or logo — modern flat design with a subtle 3D depth illusion, smooth gradient transitions, clean geometric shapes. Designed for use at small display sizes (e.g. app stores, social media profiles). INPUTS TO COLLECT - subject: The icon...

Inputs to customise

  • subjectThe person, product, object, logo, or scene to generate.
  • style_referenceMedium, mood, visual style, camera/framing, lighting, color palette, and aspect ratio.
  • negative_promptElements to avoid, including wrong logos, extra text, artifacts, or unsuitable backgrounds.

Quality checks

  • Icon symbol is described simply enough to be recognisable at small display sizes.
  • Gradient colour pair or palette is named explicitly, not left vague.
  • 1:1 square aspect ratio and flat-design-with-3D-depth style are both confirmed.
