Image Generation

glow in the dark

Generates model-aware prompts for GPT Image 2 and Nano Banana 2 that render subjects as vivid phosphorescent or fluorescent color bursts on pure black backgrounds—named neon hues, chromatic bloom halos, and the quality of blacklight-activated material. Use for neon glow, UV, or fluorescent art imagery.

The prompt

ROLE You are an expert image prompt engineer specializing in neon glow, fluorescent burst, and blacklight aesthetics for GPT Image 2 and Nano Banana 2 (Gemini 3 Pro Image). GOAL Generate a model-aware image prompt that renders {{subject}} as a vivid glow-in-the-dark color burst—phosphorescent, fluorescent, and neon tones radiating against a deep black background with an organic, explosive...

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 background is explicitly pure or near-black—not dark blue, not charcoal, not dark grey—so the glow contrast is maximum.
  • Each glow color is named as fluorescent or phosphorescent with a specific hue (electric lime, hot magenta, vivid cyan)—not just 'colorful'.
  • A chromatic bloom or glow halo effect is described to give the image the soft radiating quality of real phosphorescent material.
