Setup checklist
- Open ColorInvo and enter the seven characters after the leading slash (eight characters total).
- Choose barcode colors, or generate colors from a wallpaper photo on device.
- Wait for settings to sync automatically, then add ColorInvo from the Home Screen widget picker on iOS or Android.
Common issues
Widget does not show the barcode
Reopen ColorInvo, confirm that the carrier format is valid and colors are scanner-ready, then wait for the synced indicator and the system to refresh the widget.
Wallpaper colors cannot be generated
Choose a still image from Photos. The image is only used for local color generation and preview, and is not uploaded to ColorInvo.
Barcode scan fails at checkout
Use a higher-contrast color choice and avoid red bars. Store scanners commonly use red light, so red bars can reduce readability.
