Advanced Styling: Colored QR Codes That Actually Scan
Gone are the days of boring black-and-white QR codes. Modern branding demands color, personality, and style—while still guaranteeing 100% scannability.
The Science of Scannable Colors
QR readers need strong contrast between foreground (data modules) and background. Follow these rules:
- Dark foreground on light background (or vice versa)
- Minimum contrast ratio: 4.5:1 (our built-in warning alerts you if lower)
- Avoid similar hues (e.g., blue on purple)
- Test in both color and grayscale—some phones use B&W cameras
Style Options Explained
- Square — Classic, works everywhere
- Dot — Modern, friendly, great with logos
- Rounded — Soft, elegant, perfect for luxury brands
- Quiet Zone — Always keep at least 4 modules (our default)
