← All guidesBest Practices for QR Code Color and Contrast
Learn how to choose the right QR code colors, background colors, and contrast to ensure that your QR codes scan reliably across devices.
Choosing the right colors and ensuring proper contrast is essential for QR codes to scan reliably.
The Importance of Contrast
QR codes need to have high contrast to be scanned reliably. Dark QR codes on light backgrounds work best.
What to Avoid
- Avoid light QR codes on dark backgrounds (they can be difficult to scan on some devices).
- Avoid low-contrast colors like gray on gray or metallic ink.
- Do not place the QR code on busy or patterned backgrounds.
Choosing Colors for Your QR Code
Use black on white for maximum scan reliability. For custom colors, ensure there's enough contrast.
Testing Your QR Code Colors
Test your QR code on both iPhone and Android to ensure the color choice works well on different screens.
Exact mm/in recommendations, quiet zone rules, and print tips so your QR scans fast on real phones from typical distances.
When SVG is mandatory (printing), when PNG is fine (screens), and how resizing affects scan reliability.
Why quiet zone is non-negotiable, how to choose colors that scan, and what backgrounds (patterns, gradients) break QR detection.
Best size for table tents and wall posters, avoiding glare, and a practical checklist for menus that scan instantly in real lighting.
Pick the right error correction level for print/screens/logos. Learn the trade-off: higher correction = denser QR = needs larger print.
