Yes, QR-Codes can actually be a different color, although most QR-Codes are black and white. A QR-Code consists of small black and white fields that are put together to store and transmit information. However, the color of the fields does not determine the functionality of the QR-Code.
So there are many reasons why QR-Codes may have different colors. Although most QR-Codes are black and white, there are also many QR-Codes in other colors designed for specific purposes. However, the color of a QR-Code does not affect its functionality and ability to store and transmit information.
To change the color of a QR-Code, there are several methods:
Note, however, that the contrast between the color of the code and the background must be relatively high. Otherwise, scanners can no longer recognize the code and it becomes unusable.
