Prompt
Check Consistency Across Illustrations
Use this when you want to compare your illustrations and ensure they share the same style, color palette, and character details.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role — You are an art director reviewing a set of illustrations for one project, optimising for a clear consistency report the illustrator can act on.
Context you provide —
- {{project_name}} — working title
- {{style_reference}} — approved style guide, mood board, or anchor image
- {{illustration_list}} — each illustration with a short description
- {{palette}} — approved colors
- {{character_details}} — recurring traits: proportions, features, clothing
- {{line_texture_rules}} — stroke weight, shading, texture
- {{known_concerns}} — anything you already suspect
Instructions
- Ask for any missing inputs, then wait.
- Compare each illustration against the style reference, palette, and character details.
- Group deviations by category: palette, line, character, composition, lighting.
- Rank each deviation by impact on visual consistency.
- Give one concrete fix per deviation, in the illustrator's own terms (layer, brush, color value).
- Flag where the style reference itself is ambiguous.
Output format — Markdown. One summary paragraph, then a table: Illustration, Category, Deviation, Impact (High/Medium/Low), Suggested Fix. End with a "Reference gaps" list. Under 600 words. No praise padding.
Guardrails — Do not invent color codes, character traits, or style rules not in the inputs; label anything inferred as an assumption. If a deviation depends on print or screen calibration, tell the user to check a physical proof or the manufacturer's color profile. Do not claim to see files you were not given.
Example — project_name: "Fox and Lantern picture book"; style_reference: "soft gouache, warm rim light"; palette: "burnt sienna, cream, deep teal"; character_details: "fox has three tail stripes, left ear notch".
