AI image tools have one stubborn weakness for marketers: they forget your brand the moment a new chat starts. You paste the hex codes, describe the photo style, attach a logo, and next week you do it all again. The colours drift, the mood changes, and the social set never quite matches the website.
On 20 October 2026 Google announced a fix aimed squarely at that problem. Gemini can now save a brand style from your website, brand kit, fonts or colour palettes and reuse it with Nano Banana 2.1, its latest image model. This guide shows how to set the style up so it actually helps, the prompt that keeps outputs consistent, and where the feature still falls short.
What is Gemini's saved brand style?
Gemini's saved brand style is a stored set of your logo, colours, fonts and visual references that the Gemini app keeps and applies when Nano Banana 2.1 generates images. You upload the material once, then call the style when you need launch visuals or campaign assets, instead of re-uploading guidelines every time.
It arrived as part of a new small-business landing page in the Gemini app, described in Google's 20 October announcement. In Google's demo, as reported by Chrome Geek, the page opens with three cards: create image styles for your brand, customise Gemini with apps and skills, and create content with templates. A saved kit for a demo ceramics brand holds its logo, four colours and two fonts, and you call it up by typing an @ mention of the brand in your prompt.
Google says the hub, its marketing and finance skills and new connected apps begin rolling out globally to all Gemini app users "in the coming days". No plan tier or price was named.
Why does a saved style matter for AI marketing images?
Consistency, not quality, is what stops most teams using AI images in real campaigns. Each new chat starts from zero, so colours, lighting and composition drift between assets. A saved style turns your brand rules into persistent context, so the tenth image starts from the same place as the first.
Until now the workarounds were all manual. You kept a prompt snippet with hex codes, attached the same reference images every time, or built a long "style roster" prompt. Those still work, and our Nano Banana 2.1 consistency guide covers the reference-image approach in detail. The difference is where the rules live. With a saved style, they live in Gemini instead of in your clipboard.
That matters most for people producing visuals every week without a designer: a marketer running social for two product lines, a freelancer managing a client's launch, a small team that needs the shop banner and the Instagram post to look like the same company.
Picture a typical week for a marketer at a Hong Kong tea shop. Monday needs a promo tile for the website, Wednesday an Instagram post for a new blend, Friday a story for the weekend market stall. Without a saved style, each of those starts with a fresh prompt and a fresh set of uploads, and by Friday the greens have quietly turned teal. With a saved style, each request starts from the same palette and photo mood, and the only thing you change is the asset itself.
The saved style also sits next to connections to Canva and Adobe in the same hub, according to Google's announcement. That hints at a workflow where Gemini generates the on-brand scene and your design tool handles the final layout, although Google has not described exactly how the two connect.
How do you set up a brand style Gemini can follow?
Upload a one-page brand sheet and a few approved images rather than just your website URL. A website often contains off-brand banners and old campaigns, and Gemini will copy them faithfully. A clean sheet gives the model exact colours, fonts and do-and-don't rules to work from.
Build the sheet in any doc tool and export it as an image or PDF. Keep it to one page:
--- Colours: two or three primary hex codes and one accent, each with a short label such as "navy, backgrounds".
--- Fonts: the heading and body font names, plus a sample line of each.
--- Photo style: one sentence on lighting and mood, for example "soft natural daylight, real people, no stock-photo smiles".
--- Rules: three do lines and three don't lines, such as "never place the logo on a busy background".
--- Approved examples: three past visuals you were happy with.
Then add the logo file and the approved images alongside the sheet when you create the style. If your brand has sub-brands, create a separate style for each rather than one mixed kit. Google has not said how many styles an account can hold, so start with your main brand.
What prompt gets consistent on-brand images from Gemini?
Call the saved style by name, then specify the asset, the format, the subject, what must stay fixed and what to avoid. Leave headline text out of the image and add it later in a design tool. Short, labelled prompts give Nano Banana 2.1 less room to improvise away from your brand.
Here is a template you can adapt. Replace @YourBrand with however your saved style appears in Gemini:
Try this prompt:
Use the @YourBrand style.
ASSET: Instagram feed post for our autumn tea gift set launch.
FORMAT: 4:5 portrait.
SUBJECT: The gift box on a wooden table next to a steaming cup, morning light from the left.
KEEP: Brand colours for background and props, our photo style, logo small in the bottom-right corner.
AVOID: Any text other than the logo, extra products, cartoon style, colours outside the palette.
LEAVE SPACE: Keep the top quarter plain so I can add the headline later.
The LEAVE SPACE line is the one most people miss. Image models still make spelling and spacing mistakes with text, so the safest approach, recommended in most brand-consistency guides including AOK Marketing's, is to generate the scene and set the real type yourself in Canva, Adobe Express or PowerPoint.
For a full campaign set, keep the prompt identical and change only ASSET and FORMAT: a 16:9 website banner, a 9:16 story and a 1:1 marketplace tile. Changing one variable at a time is what keeps the set looking like a set.
Before anything goes live, run a quick review pass. Check three things on every image: whether the main colours match your hex codes when sampled with a colour picker, whether the logo is the real one and not a redrawn lookalike, and whether any stray text crept in. Image models can redraw a logo instead of copying it, so the safest habit is to place the official logo file yourself in the design tool as well.
What are the limits of Gemini's brand style today?
Google's announcement names no plan, price or region list, says nothing about how many styles you can save, and shows demo screens. Font matching in generated images is approximate. Several of the connected apps that sit next to the feature have account and country limits, so check what your own account shows before planning around it.
The honest list, based on Google's post and Digital Applied's 21 October reading of Google's help pages:
--- Rollout is gradual. "All Gemini app users, globally" is the stated audience, but it may not appear in your account in Hong Kong yet.
--- Fonts are a guide, not a guarantee. The image model renders lettering as pixels. Do not rely on it to reproduce your exact typeface.
--- Garbage in, on-brand garbage out. If the source website is off-brand, the saved style will be too. Use a clean brand sheet.
--- Connected apps have limits. Digital Applied reports that nine of the ten named connections are listed for personal Google Accounts only, the seven third-party ones are English only, and Shopify and Dropbox are listed as US only.
--- Agencies should wait. Switching between several clients' styles in one account is not documented.
How can you test Gemini's brand style in 20 minutes?
Create one style from a clean brand sheet, generate a small launch set with the same prompt, and compare every image against your real brand kit side by side. If colours, lighting and logo placement hold across all four assets, the style is ready for routine work. If not, tighten the sheet and retry.
--- Minutes 0 to 7: build the one-page brand sheet and pick three approved images.
--- Minutes 7 to 10: create the brand style in Gemini from the sheet, logo and examples.
--- Minutes 10 to 16: run the template prompt four times, changing only ASSET and FORMAT.
--- Minutes 16 to 20: lay the four images next to your brand kit. Check hex colours with a colour picker, then note what drifted.
If one element keeps drifting, add it as a KEEP line rather than rewriting the whole prompt. For edits after generation, our Midjourney edit model guide shows a change-keep-look edit prompt you can adapt for Gemini. A saved style is a strong start; your brand sheet and a quick check are what keep it honest. We understand AI. We understand you better. With UD by your side, AI doesn't feel cold.
