Why QR contrast matters

QR scanners need clear separation between dark modules and the light background. Low-contrast brand colors, reversed colors, transparent backgrounds, and textured surfaces can make a QR code fail in real lighting.

Practical rules

Use dark foreground modules on a light background.
Keep a clean quiet zone around the QR code.
Use higher error correction when adding logos or printing outdoors.
Run the QR quality test after exporting the final image.
