Midjourney and image AI prompts that stay on brand.

One brand prompt block, a few reference images and a check. That is what keeps AI images looking like you.

Image AI stays on brand when every prompt starts from the same brand block: your colours in words, your light, your mood, your camera style and what you never show. Then you add the same reference images every time.

In Midjourney that means a fixed prompt block plus style references. In ChatGPT, Gemini and other tools it means the same block plus reference uploads. Below are the block, 12 prompts to copy and a check.

Why AI images drift off brand.

Each prompt starts from zero. The tool does not remember your brand unless you bring it.

Drift 1

Different words each time

One person writes "moody", another writes "dark and calm". The tool reads them as two looks.

Drift 2

No reference images

Without references, the tool falls back to its own house style. Many brands then look the same.

Drift 3

No check at the end

Nobody compares the image with the brand rules before it goes out.

This is the same reason AI startups look the same. The fix starts with clear visual identity rules.

Write one brand prompt block.

Write it once. Paste it at the end of every image prompt. Keep it in your brand rules.

Brand prompt block template

[subject of this image], [action or scene].
Style: [photo / 3D render / flat illustration], [camera: e.g. 35mm, eye level, shallow depth].
Light: [e.g. soft daylight from the left / dark studio with one hard light].
Colours: [main colour in words, e.g. deep green], [second colour], mostly [neutral: off-white / near-black].
Mood: [3 words, e.g. calm, precise, human].
Background: [plain / real office / abstract texture].
Never: [things you never show: stock handshakes, glowing brains, robots, blue neon, text in the image].

Write colours as words, not only hex codes. Image tools follow "deep green with off-white" better than a code. Then check the colour in the final file.

--oref	Omni Reference: keeps a person or object from an image	Keep a product or a mascot the same
Moodboards	A personal style built from images you choose	One moodboard per brand, shared with the team
--ar	Aspect ratio	Fix the sizes you use: 1:1, 4:5, 16:9

12 on-brand image prompts to copy.

Each one ends with your brand block. In Midjourney, add your style references too.

Twelve on-brand image prompts

1. Hero image for our homepage: [product] in use by [who], in [place]. [brand block]
2. LinkedIn post background, plenty of empty space on the left for a headline. [brand block]
3. Abstract texture that feels like [one brand word], for slide backgrounds. [brand block]
4. Team at work around a laptop, natural and unposed, faces not the focus. [brand block]
5. Close-up of hands using [product] on [device]. [brand block]
6. Event banner background for [event], wide, calm centre. [brand block]
7. Simple 3D object that stands for [idea, e.g. security as a closed shape], no text. [brand block]
8. Blog cover for an article about [topic], one clear subject, no text. [brand block]
9. Office or workspace that fits our brand, no people, morning light. [brand block]
10. Icon-style illustration of [idea], flat, two colours from our palette. [brand block]
11. Same scene as the reference image, but at night / in winter / in a different city. [brand block]
12. Five versions of this image with different crops for 1:1, 4:5 and 16:9. [brand block]

In a Brand OS Portal, images are checked against the brand look before they go out.

The same system in ChatGPT, Gemini and other tools.

The brand block works in any image tool. Paste it as text, then upload your 2-3 reference images and say: "Match the light, colours and mood of these images."

Most tools can now edit an image you upload. That is often better than starting from zero: take an approved brand photo and ask for a new scene in the same look. Read Gemini image tools for brand assets for what works there.

For logos, keep AI to ideas and sketches. See ChatGPT prompts for logo design for why.

Check every AI image before it goes out.

Tick what is true. Your ticks stay on this device.

The colours match the brand palette
The light and mood match the reference images
Nothing from the "never" list is in it
No fake text, logos or letters in the image
Hands, faces and products look right up close
It does not copy a real brand, artist or person
The crop fits the size you need
Someone who knows the brand said yes

How do I keep Midjourney images consistent?

Use the same brand prompt block every time, add the same 2-3 style reference images with --sref, and keep one style weight for the whole team.

What is --sref in Midjourney?

It is the style reference setting. You add image links or a style code, and Midjourney copies the look of those images into the new one.

Can I use hex codes in image prompts?

You can add them, but describe the colours in words too. Image tools follow words like "deep green and off-white" better. Always check the colour in the final image.

Can I make my logo with Midjourney?

You can make logo ideas and sketches. The output is a picture, not a clean vector file, so a designer still needs to draw the final logo. See logo design.

Do these prompts work in ChatGPT and Gemini?

Yes. Paste the same brand block and upload your reference images. The settings like --sref are Midjourney only.

Who should own the brand prompt block?

One person, often in marketing or design. Keep it next to your brand rules so it is updated when the brand changes.
