Avoid custom QR colors that look stylish but scan poorly.
Contrast result
16.5:1StrongChecking contrast before print catches problems that look fine on screen. Brand colors can look polished in a mockup and still fail under office lighting, glossy paper, or a scratched phone camera lens.
A dark foreground on a light background is the safest choice. Black on white is still the most reliable for print.
Yes, but keep the foreground dark enough and the background light enough. Test the exported code before printing.
Some scanners handle them, but they are less forgiving. Use them only after testing the exact printed piece.
Yes, if the foreground is clearly darker than the background and the quiet zone stays clean. Pale brand colors, gradients and busy backgrounds need extra testing.
Aim for at least a 4.5:1 contrast ratio between the dark modules and the background. Higher is better, especially for outdoor signs or glossy materials. A quick test: if the code looks faint in grayscale, the contrast is too low.
Yes, as long as the foreground stays clearly darker than the background. Dark navy, forest green, or deep red on white usually work fine. Avoid pastel on pastel or two mid-tone colors that look similar when desaturated.
Not reliably. Some newer phone cameras handle light modules on a dark background, but many older devices and third party scanner apps expect dark on light. Stick with dark foreground on light background unless you have tested across several devices.
Plan how large a QR code should be before it goes on a sign, label, or poster.
Prepare QR codes for label-style printing and repeated physical placement.
Make a clean QR flyer for counters, walls, events, and handouts.
Design a folded table tent with QR panels for restaurants, events, and service desks.
