Customize QR colors and logos with confidence
QR puli ·
Learn how dot contrast, white backgrounds, logo size and error correction affect colorful QR codes, with practical checks before sharing.
Keep the pattern readable
Choose a dark pattern on a light background to give your QR code clear contrast. Use your brand colors, keep a center logo compact and leave the three corner markers easy to see.

Give your QR code a recognizable identity. Use your website’s artwork, add a logo in the center, or turn an image into the QR design. Customize the colors and dot patterns to match your brand, then download your code for free.

A center logo covers some encoded information. Error correction can tolerate some damage, but that does not mean an arbitrary percentage of the QR can safely be covered. Keep logos compact and recognizable, and never cover the finder corners. A simple mark often survives small prints better than detailed artwork.
Treat contrast protection as one check
QR puli uses a conservative color-contrast guard and a decoder check before export. A text contrast ratio is not a complete QR scannability standard. Pattern density, gradients, image compression and the camera also matter. Test the exact downloaded file and final print.
Make the destination accessible too
Print a short readable URL or another contact method beside the QR where practical. Tell people what scanning does, such as “View the menu.” On social media, include a clickable destination link as well as the QR image. This helps people using screen readers or viewing the post on the same phone they would use to scan.
