One paragraph appended to every prompt — and the images stop drifting apart.

Midjourney / ChatGPT (vision)generationbrandconsistency
You are an art director. Build a standing prefix for image-generation prompts.

Brand: {name and what it does}
Mood: {three or four words}
Brand colours: {hex or names}
Examples you like: {links or descriptions}
What must never appear: {what grates}

Deliver:
1. A 40-60 word prefix: light, materials, palette, optics, composition. It gets appended to any request.
2. A "never" list of explicit exclusions. Without one the model folds in stock cliches — lens flare, perfect smiles, glass spheres.
3. Three complete example prompts: a cover, a product, a background.
4. What changes from image to image and what is never touched.

The prefix must work without the brand name inside it: the generator does not know the brand and will start guessing from the sound of it.

Prefix: soft diffused daylight, matte surfaces, deep violet and near-black palette, 50mm lens, shallow depth, generous negative space, calm composition, no text. Never: lens flare, glossy 3D spheres, stock smiles, neon grid, cluttered background. Never touch: light and palette. Change: subject and angle.

Rules that make ten drawings read as one set rather than ten discoveries.

Midjourney / ChatGPT (vision)illustrationstyleset
You are an art director. Define an illustration style for a product.

Product: {what it is}
Where the drawings go: {empty states, blog, email, social}
Mood: {three words}
Palette: {colours}

Set the rules:
1. Stroke weight, whether there is an outline, fill — flat or textured.
2. People: present or not. If present, how abstracted. Realistic faces age fastest and date the work first.
3. Perspective: front-on, isometric, top-down. One for the whole set.
4. How many colours per drawing — as a ceiling, not a preference.
5. What the drawing does: explains, decorates, or leads the eye. Detail level follows from that.
6. Three ready prompts showing the range: simple, medium, complex scene.
7. A check for any new drawing: three questions that prove it belongs to the set.

Another person must be able to apply these rules. "Friendly and modern" cannot be applied.

2px stroke, no outline, flat fill with 6% grain. People abstracted: the head is a circle with no features. Realistic faces look like clip art within a year. Isometric, 30 degrees, one angle for the set. No more than four colours plus the ground. Check: one stroke weight? Same angle? Four colours or fewer?

Twenty minutes down a list, and half the client's notes never happen.

ChatGPT (vision) / Claudereviewlayoutquality
You are an art director. Review a layout the way you would before showing a client.

Layout: {describe or attach}
What it is for: {the goal}
Who sees it: {client, team, public}

Walk the list and say where it does not hold:
1. What is seen first. Whether that matches what should be primary.
2. Alignment: what is almost on the grid — almost is worse than plainly off.
3. Spacing: how many distinct values are in use. More than five means some are accidental.
4. Type sizes: how many. More than six means there is no scale.
5. Legibility: where text sits on an image with no plate, where contrast drops under 4.5.
6. What happens to the longest name, the biggest number, the missing image.
7. The one place where you chose pretty over clear. There always is one.

Do not compliment. The job is to find what the client will catch, before they do.

The image is seen first, but the price is the point. The eye goes the wrong way. Nine spacing values: 12, 14, 16, 20, 24, 28, 32, 40, 48. Fourteen and twenty-eight are accidents — fold them into the scale. Text over the photo at the bottom: contrast 3.1. On a light frame it will not read at all. Pretty over clear: the caption is letter-spaced and reads as a heading.
