The prompt
Define a visual style guide for AI image generation.
Brand: {{describe}}
Existing colors: {{hex_codes_or_descriptions}}
Visual styles I admire: {{name_2_3_references}}
Where images will be used: {{website_social_ads}}
Always include: {{people_nature_abstract_product}}
Always avoid: {{stock_photo_look_certain_colors_faces_te}}
Please create:
1. A base style string to append to all prompts
2. Color palette guidance
3. Lighting and mood direction
4. Composition rules
5. 3 sample full prompts for common use cases Why this works
Building a visual style guide as a structured document ensures anyone on the team can generate on-brand images without tribal knowledge. The composition rules and lighting direction sections move beyond colour and mood to the structural elements that make a visual suite feel cohesive. The three sample prompts give the team working templates rather than just principles.
Risks & review
AI image generation tools interpret the same style guidance differently, and consistency can drift over a session. Test the style guide with at least 20 generations before treating it as finalised — you'll discover which elements hold up and which need more specific language.
