QR Code Colors & Design
Definition: QR code colors refer to customizing the foreground (module) and background colors of a QR code while maintaining sufficient contrast for reliable scanning.
QR codes don't have to be black and white! You can customize colors to match your brand. The key rule is maintaining high contrast: dark foreground on light background. Avoid light-on-light or dark-on-dark combinations. Never invert colors (light foreground on dark background) as many scanners can't read inverted codes. Always test colored codes on multiple devices.
Key points
- Dark foreground on light background always
- Minimum 40% contrast ratio recommended
- Never invert (light on dark) — many scanners fail
- Test on 3+ devices after adding color
- Gradient backgrounds can cause scanning issues
- The finder patterns (corner squares) should stay high-contrast
Frequently asked questions
Can I make a QR code any color?
You can use any color as long as the foreground is significantly darker than the background. Dark blue on white, dark green on light yellow — all work well.
Why won't my colored QR code scan?
Most likely insufficient contrast. Ensure the foreground is clearly darker than the background. Avoid red on green (colorblind users) and light-on-light combos.
Can I use a gradient in a QR code?
Foreground gradients can work if all parts maintain contrast. Background gradients are risky — any area with insufficient contrast will cause scanning failures.
