The Rundown:

In this guide you’ll learn to create a full brand kit pdf, several logo variations and social media templates using Nano Banana Pro.

Who is this useful for:

• Business owners hiring a graphic designer or social media intern
• Vibe coders building out a new app
• Any team with disorganized style guides

What You Will Build

Setup (5 minutes)

Step 1: Open Google AI Studio

1. Go to aistudio.google.com
2. Click "playground"
3. Connect a paid api key if you haven’t yet

Step 2: Add System Instructions

Click on "System instructions" and paste:

GENERATION PRINCIPLES: When I request brand assets, structure your prompts using:

1. SUBJECT & PURPOSE: Clearly describe what we're creating and who it's for (e.g., "A logo for freelance designers who value both aesthetics and professionalism")
2. VISUAL DESCRIPTION: Use natural language and full sentences. Describe composition, lighting, materials, textures, and spatial relationships as if briefing a human designer.
3. BRAND CONSISTENCY MARKERS: Reference the established color palette, typography style, visual mood, and design language we've agreed upon.
4. CONTEXT & RATIONALE: Explain WHY certain design choices support the brand strategy.

WORKFLOW APPROACH:

• Start with foundational assets (logo, color palette) before moving to applications
• Suggest variations that maintain brand integrity while adapting to different contexts
• Proactively identify when an asset needs adjustment for its specific use case (e.g., social profile vs. banner)

QUALITY STANDARDS:

• Leverage Nano Banana Pro's strengths: precise typography, data visualization, consistent branding, multi-image composition
• Avoid keyword-style prompts like "logo, modern, clean, blue"
• Instead use: "A contemporary logo mark that combines geometric precision with organic flow, rendered in deep navy with coral accents, designed to appeal to creative professionals who appreciate sophisticated minimalism"

Step 3: Create Your Folder Structure

To stay organized, create a folder on your computer for your brand kit. Put these subfolders in it:

[Brand Name] Brand Kit/

├── Logo Files/

├── Social Assets/

└── Brand Kit Slides/

Phase 1: Brand Discovery (5 minutes)

Your First Message to Gemini:

I need to create a complete brand kit for my business. Let me give you the basics:

Business name: [YOUR BUSINESS NAME] What we do: [ONE SENTENCE - e.g., "Productivity app that tracks time and generates invoices for freelancers"] Target customer: [WHO + THEIR PAIN - e.g., "Freelance designers (25-40) who waste hours on admin work"] Brand personality: [3 ADJECTIVES - e.g., "Professional, approachable, energetic"]

Interview me briefly to understand my brand, then we'll start generating assets. Keep it to 3-5 focused questions. Make sure you interview me about tagline(s) we can use for the brand.

What happens next:

• Gemini will ask you 3-5 clarifying questions
• Answer them naturally (don't overthink it)
• This builds context so all assets stay consistent

Pro Tip: The more time you spend here going back and forth with Gemini, the better your end results will be.

Phase 2: Generate Logo Options (10 minutes)

After the interview, send this message:

Based on our conversation, generate 4 distinct logo concepts for [YOUR BRAND NAME].

Show them in a clean 2x2 grid, labeled "Option 1" through "Option 4". Each should explore a different design direction while staying true to our brand positioning.

Use Nano Banana Pro to generate this as a professional presentation slide with the title "Logo Concepts" at the top.

What you'll get:

Phase 3: Extract Your Chosen Logo (15 minutes)

Use the prompts in this section to get all the logo variations you will need.

Message 1: Primary Logo

I love Option [NUMBER]. Create the primary, full-color version of this logo as a standalone, high-quality asset.

This is the main version we'll use most frequently. Show it on a clean white background with adequate spacing. Professional execution ready for all brand applications.

What to do:

1. Download and save as "Logo_Primary.png" in Logo Files folder

Message 2: Secondary/Simplified Logo

Now create a simplified version of this logo optimized for small sizes like social media profile pictures and favicons.

This should be streamlined while remaining recognizable - could be icon-only or a condensed version. Must work well at 48x48 pixels and in circular crops.

What to do:

1. Download and save as "Logo_Secondary.png" in Logo Files folder

Message 3: Monochrome Black

Create a monochrome black version of our logo for situations where color printing isn't available - photocopies, faxes, newspaper ads, embossing.

Solid black only, no gradients or gray tones. Same design, just converted to pure black on white.

What to do:

1. Download and save as "Logo_Monochrome_Black.png" in Logo Files folder

Message 4: Monochrome Reverse (White)

Create a monochrome reverse version - white logo on a dark background. This is for placing our logo on dark photography, dark websites, or dark branded materials.

Show it on a dark background so I can see the contrast clearly.

What to do:

1. Download and save as "Logo_Monochrome_White.png" in Logo Files folder

Message 5: Icon Only

Create an icon-only version (just the symbol/mark without the wordmark) for extremely small applications like app icons, favicons, and social media profiles.

Should work perfectly in a square format and remain recognizable as part of our brand.

What to do:

1. Download and save as "Logo_Icon.png" in Logo Files folder

Message 6: Logo System Overview Slide

Make sure you switch your system settings aspect ratio to 16:9 for slides.

Now create a professional "Logo System" slide showing all 5 variations we just created in a clean grid:

1. Primary (full color)
2. Secondary/Simplified
3. Monochrome Black
4. Monochrome White (on dark background)
5. Icon Only

Label each clearly and add minimum size specs: "Minimum width: 120px for primary, 48px for icon"

Make this look like a professional brand guidelines page.

What to do:

1. Download and save as "Slide_03_LogoSystem.png" in Brand Kit Slides folder

Going Further:

To make use of your brand kit, take the logos, typography color scheme and create a brand kit in Canva. That way anytime you build an ad or social post, you’ll have your new assets at your fingertips! If you don’t use Canva, you can create a custom slide theme in Google Slides by going to Slide > Edit Theme.
