How to Write Brand Guidelines That AI Image Tools Actually Follow

Quick answer: AI tools follow concrete words, not brand adjectives. Turn your guidelines into a short visual spec: light, lens, colour values, styling rules and banned elements, then reuse it in every prompt.

Step by step

1. Collect 10 approved brand images and describe what they share.
2. Translate adjectives into camera words: 'warm' becomes 3200K side light.
3. List exact colours as hex values and name where they appear.
4. Write a 'never' list: props, poses, filters you reject.
5. Save it as a reusable brand look and test it on five products.

Prompt to copy

Brand look: soft window light from the left, 50mm lens at eye level, warm neutral palette (#E9E1D3, #2B2B2B, accent #C8F25A), matte surfaces, natural skin texture, no lens flare, no neon, no busy props.

Replace the words in brackets with your own product, model or brief.

Common mistakes

• Changing light direction between images in one set
• Vague words like 'premium' or 'beautiful' instead of light, lens and colour
• Publishing without checking product details at full size

FAQ

Why does AI ignore my brand words?

Words like 'premium' are vague. Light direction, lens and colour values are things the model can render.

How long should the spec be?

One short paragraph you can paste at the end of every prompt.

Can I keep colours exact?

Use hex values and check output; our palette tool turns hex codes into prompt wording.
