Create a one-page brand kit and test it on three different assets.
- Create a one-page brand kit and test it on three different assets.
Every new request starts the same way: “make it modern but friendly, with my blue”. The result differs each time because the description is loose and lives only in your head. A brand kit fixes that by putting the decisions in one reusable page.
It does not need to be fancy. Logo rules, exact colours, two fonts, a few tone words and a short list of dos and don’ts are enough. Then the same page becomes a header you paste into any AI tool, with constraints stated first, as Google’s prompting guidance suggests.
The examples below are illustrative exercises, not recorded results from any tool. Sources were checked on 24 October 2026; menus, limits and prices change, so confirm details on the linked pages.
Before you start
- Your logo file and current colours (hex codes)
- The two fonts you actually use
- Three assets you want to make, such as a post, a banner and a thumbnail

Documentation-based review · 2026-10-24
Primary documentation and official guidance checked on 24 October 2026. Examples, checks and exercises are original illustrations, not recorded tool tests. Cover artwork is a conceptual illustration.
Collect the facts, not the feelings
Gather the logo file and its clear-space and minimum-size rules, exact hex codes with their roles, two fonts with sizes for headings and body, three tone words and five dos and don’ts. Check your text colours pass contrast. Anything you cannot name exactly is not part of the kit yet.
Check your result
The kit has exact hex codes, two named fonts, three tone words and five dos and don’ts.
Turn it into a one-page kit and an AI header
Ask the AI to lay out your facts as a one-page kit and to write a short “prompt header” of about 80 words that you can paste before any design request. Tell it to use only the facts you provide and not to add colours, fonts or claims.
Create a one-page brand kit using ONLY the facts below. Sections: Logo rules, Colours (hex and role), Fonts, Tone words, Do, Don’t. Then write an 80-word “brand header” I can paste before design prompts. Do not add colours, fonts or slogans.
Facts:
[paste your facts]Example / expected result
Illustrative example; not a recorded model result.
“Brand: Greenleaf Café. Colours: #0F766E headings, #1F2937 text, #FFFFFF background. Fonts: Poppins headings, Inter body. Tone: warm, clear, never pushy. Do keep logos clear of text. Don’t use gradients.”
Check your result
You have a one-page kit and an 80-word header that contains nothing you did not supply.
Test the kit on three assets and tick a checklist
Paste the header into three real requests, such as a social post, a banner and a thumbnail. For each, check colours against the hex codes, fonts, logo placement and tone. Where the result broke a rule, edit the kit’s wording and try again until all three pass.
Check your result
All three assets follow the colours, fonts, logo rules and tone, and the kit has been corrected where one failed.
When it goes wrong
AI tools may still substitute a similar font or shade, so check the exact codes. A kit is a living page; date it and update it when branding changes. Never paste unreleased brand assets into tools you have not checked.
Make it your own
Build a kit for a real or fictional small brand, make three assets with the header, and list which rule each tool broke at least once.
