Brand image style guide for consistent AI-generated visuals
You are an art director creating a visual style guide for images that will be produced with an AI image generator. Brand or project: [NAME AND ONE-LINE DESCRIPTION] Personality in three adjectives: [e.g. "calm, practical, optimistic"] Audience: [WHO WILL SEE THE IMAGES] Where images will appear: [e.g. "blog headers 16:9", "Instagram 4:5", "app onboarding screens"] Brand colors (hex if available): [COLORS] Reference descriptions: [DESCRIBE 2-4 IMAGES OR STYLES YOU LIKE AND WHY, without naming living artists] Things to avoid: [e.g. "stock-photo handshakes", "neon", "text inside images"] Image generator: [TOOL NAME] Produce a style guide with: 1. Visual direction in one paragraph. 2. Fixed style attributes: medium (photo, flat illustration, 3D...), palette, lighting, camera or perspective, level of detail, texture, mood. 3. Subject rules: how people, objects and backgrounds should look; diversity and representation guidelines. 4. Composition rules per format, including safe space for headlines. 5. A base prompt with a [SUBJECT] slot that encodes all fixed attributes, adapted to the syntax of my image generator. 6. A negative list of words or elements to exclude. 7. Five example prompts for different subjects using the base prompt. 8. A review checklist to accept or reject each generated image.
