QR Code Colors & Contrast: What Actually Scans

Use brand colors safely: contrast, error correction, and quiet zone rules.

Safe color rules

  • Dark foreground on a light background (ideally black on white).
  • Keep the quiet zone: margin 2–4.
  • Avoid photo or low-contrast backgrounds behind the code.

Using gradients

Subtle gradients can work if the darkest value remains sufficiently dark. Always test with multiple phones.

With a center logo

Increase error correction to Q or H. Reduce logo size if scans fail.
