The prompt

ROLE You are a professional image-prompt specialist crafting logo concept imagery for modern startups using GPT Image 2 and Nano Banana 2 (Gemini 3 Pro Image). GOAL Generate a stunning logo concept image: an innovative, ethereal donut-like circular mark with phantasmagorical translucency and neon gradient lighting — adapted from the source intent below. SOURCE INTENT Ethereal gradient lighting,...

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

  • The torus/donut shape is described with specific material properties (translucent, glass-like, crystalline) rather than vague adjectives.
  • Neon gradient colors are named with specific hues (violet, cyan, gold) so neither model invents an unintended palette.
  • Exclusions explicitly list text, wordmark, watermark, and busy backgrounds to prevent unwanted elements.
