QR codes aren’t just black-and-white squares anymore—they’re a powerful branding tool. Today, businesses use colored QR codes on menus, packaging, flyers, websites, and even product boxes to stand out and increase scan rates.
In this complete guide, you’ll learn how to design a custom QR code with colors, how to avoid common mistakes, and how to create your own vibrant QR code using FreeQRTools.
What Is a Custom QR Code?
A custom QR code is a QR code that has been designed using colors, shapes, logos, and brand elements while still remaining fully scannable.
Standard vs. Custom QR Code
- Standard: Black foreground, white background
- Custom: Colored QR codes with logos, patterns, gradients, or shaped corners
Why Brands Use Colored QR Codes
- Better visual appeal
- Stronger branding
- Higher scan rate
- Makes packaging and posters look premium
- Helps differentiate from competitors
Can QR Codes Have Colors?
Yes. QR codes can have one or multiple colors—as long as contrast and structure are maintained.
How Colors Affect Scanning
QR scanners detect differences between dark modules (foreground) and light areas (background).
If contrast is low, scanning fails.
Common Myths About Colored QR Codes
- ❌ “Colored QR codes don’t work.”
- ❌ “QR codes need to stay black.”
- ❌ “Logos break the QR code.”
- ❌ “Multiple colors confuse scanners.”
All false. With correct design rules, colorful QR codes work perfectly.
Best Practices Before Designing a Colored QR Code
1. Use High Contrast Colors
Rule of thumb:
Dark foreground + Light background
Great combinations:
- Dark Blue on White
- Black on Light Yellow
- Deep Green on Cream
Avoid:
- Light foreground colors
- Dark backgrounds
- Color pairs with similar brightness
2. Avoid Neon, Metallic, or Pastel Foreground Colors
These colors reflect too much (or too little) light, confusing the scanner.
3. Maintain the Quiet Zone
The quiet zone is the blank margin around the QR code.
Never add colors, icons, or images here.
4. Use High Error Correction
If you plan to add a logo, set error correction to:
Level H (30% correction)
How to Design a Custom QR Code With Colors (Step-By-Step)
Below is the exact process you can follow using FreeQRTools.
Step 1 — Choose the Type: Static vs Dynamic
- Static QR Code: Fixed data
- Dynamic QR Code: Editable data + tracking
To create a base code, use our free QR code generator.
For advanced branding or updating links later, use a dynamic QR code.
Step 2 — Choose Your Color Palette
Use your brand colors or pick a visually strong combination.
Tips:
- Foreground must be darker than background
- Pastel colors only work as background
- Test readability on both bright and dim screens
Step 3 — Add Your Logo (Optional but Recommended)
Adding a logo improves recognition and trust.
Use:
QR code with logo generator
Logo placement rules:
- Keep logo small
- Use transparent PNG
- Increase error correction
Step 4 — Customize Shapes and Patterns
You can adjust:
- Dot shapes
- Corner styles
- Patterns (rounded, square, smooth)
- Color gradients
Rounded patterns look modern and improve brand fit.
Step 5 — Test Your QR Code Thoroughly
Test using:
- iPhone camera
- Samsung camera
- Google Lens
- Multiple lighting conditions
If scanning is slow:
- Increase contrast
- Make foreground darker
- Reduce patterns
- Resize the QR code

Step 6 — Export in High Resolution
For print:
- Download in SVG or EPS
- Minimum 300 DPI
For digital:
- PNG is fine
- Use at least 1024×1024 px
Examples of Good and Bad Color Combinations
✔ Good Color Combinations
- Dark Purple on White
- Navy on Beige
- Black on Light Yellow
- Dark Green on Cream
✘ Bad Color Combinations
- Light Blue on White
- White on Black (inverted pattern)
- Neon Pink foreground
- Dark Blue on Dark Gray
Technical Guidelines for Print-Ready QR Codes
Minimum Size
- 2 cm × 2 cm: Small cards
- 4 cm × 4 cm: Packaging
- 15+ cm: Posters / billboards
DPI
- Print: 300 DPI
- Posters: 500 DPI
Quiet Zone Requirement
Leave at least 4 modules of white space around the code.
Surface Tips
- Avoid glossy surfaces—light reflection blocks scanning
- Avoid gradients behind the QR code
Common Mistakes to Avoid
- Using low-contrast colors
- Adding background patterns
- Stretching the QR code
- Oversized logos covering modules
- Removing too many dots for design aesthetics
These reduce scan reliability.
