The prompt
ROLE You are an expert image prompt engineer specializing in high-impact color-palette portrait photography for GPT Image 2 and Nano Banana 2 (Gemini 3 Pro Image). GOAL Generate a model-aware image prompt that renders {{subject}} using a strict electric blue, silver, and black palette—bold, high-contrast, technologically charged portrait aesthetic with controlled color discipline—using...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
- All three palette colors have explicitly assigned roles—electric blue as accent, silver as metallic mid-tone, black as shadow and background.
- A directed light source reinforces the electric blue palette rather than using neutral white light.
- Color swatch panels and any warm tones are explicitly excluded so the output stays within the palette discipline.
