1. The Golden Rule: Simplicity Wins
The most important design principle for favicons is simplicity. Your favicon will be displayed as small as 16x16 pixels - about the size of a pencil eraser.
✅ Simple favicon designs work because:
- They remain recognizable at tiny sizes
- They load faster (smaller file size)
- They're memorable and distinctive
- They work on any background color
What to Avoid
- ❌ Complex gradients (become muddy at small sizes)
- ❌ Fine details or thin lines (disappear or blur)
- ❌ Multiple elements crowded together
- ❌ Text or letters (unreadable below 32x32)
- ❌ Photographic images (lose clarity when scaled)
2. Color Psychology in Favicon Design
Choose Colors Strategically
Colors evoke emotions and associations. Choose your favicon colors based on your brand and industry:
🔴 Red
Emotions: Energy, urgency, excitement
Best for: News, entertainment, food delivery, sales
🔵 Blue
Emotions: Trust, calm, professionalism
Best for: Finance, healthcare, technology, corporate
🟢 Green
Emotions: Growth, nature, health
Best for: Environment, health, finance (growth), organic
🟠 Orange
Emotions: Creativity, enthusiasm, affordability
Best for: E-commerce, creative services, fun brands
🟣 Purple
Emotions: Luxury, creativity, wisdom
Best for: Premium brands, beauty, education
⚫ Black
Emotions: Sophistication, elegance, power
Best for: Luxury brands, fashion, high-end products
High Contrast is Essential
Your favicon needs to be visible on:
- Light browser themes (white/gray backgrounds)
- Dark browser themes (black/dark gray backgrounds)
- Colored browser chrome (some browsers tint tab bars)
Pro tip: Add a subtle border or background shape if your logo is a single color.
3. Shape Psychology
Geometric Shapes Convey Meaning
- Circles: Unity, community, completeness (social networks, communication)
- Squares: Stability, trust, professionalism (banks, corporate)
- Triangles: Energy, direction, innovation (tech, startups)
- Rounded rectangles: Modern, approachable (apps, SaaS)
4. Typography in Favicons
Single Letters Can Work
If using text, follow these rules:
- Use only ONE letter (your brand initial)
- Choose a bold, thick font (thin fonts disappear)
- Minimum size: 32x32 for any text to be readable
- Add a background shape for contrast
- Test at 16x16 - if unclear, use a symbol instead
⚠️ Warning About Text
Most favicon design experts recommend AGAINST using text. Symbols and shapes are more recognizable at small sizes. If you must use text, test extensively at 16x16 pixels.
5. Brand Consistency
Your Favicon Should Match Your Brand
- Use your brand's primary color
- Extract a simplified symbol from your logo
- Maintain visual connection to full logo
- Keep the same style (modern, playful, serious, etc.)
Don't Just Shrink Your Logo
A common mistake is simply resizing your full logo to 16x16. Instead:
- Extract the most recognizable element from your logo
- Simplify complex shapes
- Increase line weights
- Remove fine details
- Create a "favicon version" of your brand
6. Testing Your Design
Essential Design Tests
Before finalizing your favicon, run through these critical tests to ensure it works perfectly:
The Squint Test
View your favicon at actual size (16x16), step back, and squint.
Pass: Can you still identify it? If not, simplify further.
Multiple Tab Test
Open 10-15 browser tabs with different websites.
Pass: Can you quickly spot your favicon? Should take less than 1 second.
Background Test
Test on white, black, gray, and colored backgrounds.
Pass: Visible and recognizable on all backgrounds.

9. Common Design Mistakes
❌ Avoid These Mistakes
- Too much detail: Complex designs become blurry blobs
- Low contrast: Light icon on light background disappears
- Multiple colors: More than 3 colors looks chaotic at small size
- Generic symbols: Using common stock icons (house, gear, etc.)
- No testing: Not viewing at actual 16x16 size before launch
- Wrong file format: Using JPEG (no transparency) instead of PNG
10. Iteration & Improvement

Once live, monitor user engagement:
- Bookmark rates
- Return visit rates
- User feedback
- Recognition in user testing
When to Redesign
Consider updating your favicon when:
- Your brand undergoes a major redesign
- It doesn't stand out among competitors
- User testing shows low recognition
- Your brand colors or logo change
